Hello, I'd like to the same you did, but with the model M711. This is my first attempt reverse engineering something, so I'm having a hard time starting it. After setting up the VM and Wireshark, I was able to capture some packets after changing values in the original software, but all packages were very small (average of 80 bytes) and were nothing like the dump found in your file "documentation/default-annotated". Am I doing something wrong, or are the packages meant to be this size, and if so, how should I concat them to a better understending of the protocol.

Edit: just saw the README.md inside the documentation folder and it was very clarifying.

I'm glad that the README helped, if you have any other questions feel free to ask.

I would recommend starting by capturing the data and writing a simple program to open the mouse, send the captured data, and close the mouse. After that works, the main work is capturing data for different settings, running diff on the captures and changing the correct values in the data.

Would you prefer to add support for the M711 to this program, or to have a separate program? I am open to any pull requests, and if you want to add support to this program i would look in to the required changes to support multiple mice.

I have added experimental support for the M711, there are still a few features missing because i don't have any captured data for them, and nothing is tested. I am leaving this issue open for now, in case you want to try it out and report what is broken and what works.

Jul 31 '20 16:07 dokutan

I'm sorry for taking so long to answer, I've made quite a nice progress, and I'd be willing add support for the M711 to your program, or to have a separate program. It really depends a lot on what is best. I will checkout the support you have added and comment and collaborate with it. The only problem is that I am very busy nowadays because of work and college, so for now there is not much I can do. But in the future be assured to hear back from me.

Jul 31 '20 19:07 rolimans

As there already is initial support for the M711 (and others) in this program, i think it is the best (and easiest) to have support for these mice in one program, and would be glad about any contribution and collaboration towards better hardware support. Feel free to take your time, and whenever you are ready, open a pull request. Furthermore if you have any initial code or captured data, feel free to share it, maybe i can use it to implement the missing features if you currently lack the time to do so.

Hey @dokutan I bought a Mouse Cobra M711. Is there any data capture/commands that i could run to help on improving this device support?

Yes, these are the things that you can try:

To get a first impression about the capabilities of the mouse, run mouse_m908 -R - and mouse_m908 -D -
Test the features that are already implemented (see the list in the README), for features that don't work or are not implemented for thew M711 try the generic backend with the -M generic option. I strongly recommend that you have the official software available (in a VM) because there is a small chance that changing the settings could make the mouse unusable (e.g. no movement in one direction).
If the previous steps were not sufficient to implement all features, you can capture the USB data sent by the official software with wireshark.

A few links that i copied from a previous issue about the capturing process: https://bytepunk.wordpress.com/2017/03/25/reverse-engineering-a-usb-mouse/ https://github.com/pez2001/razer_chroma_drivers/wiki/Reverse-Engineering-USB-Protocol https://github.com/dokutan/rgb_keyboard/tree/master/doc

That should be all, just ask if there are any questions remaining.

Feb 08 '21 16:02 dokutan

I've had some progress, but had to leave this project on hold for a while because of work and univertsity. A lot of settings from the m908 work right away with the m711 (same config bytes). I have some notes from when I was reverse engineering it myself, but I can barely understand them, so it probably won't be of much help.

Feb 08 '21 21:02 rolimans

No problem, that a lot of settings work gives me hope that it shouldn't be to dificult to implement the differing features (mainly different buttons i would assume), if you could post your notes i would have a look, we don't know if they are helpful unless i try.

These are the notes, they are confusing as I said. The numbers aside the rgb modes are the needed bytes to be sent for each mode (if I'm not mistaken). I just cant remember the position of those bytes.

Feb 08 '21 21:02 rolimans

Checking the diffs I can see a big addition in data.cpp. I can't remember if I did those but it seems so. The code follows:

std::map<std::string, uint8_t> mouse_m908::_c_windows_only_actions = {
	{"basic_cut", 0x11},
	{"basic_copy", 0x12},

Thanks, that was quite helpful. A bit of information for reference: the LED modes seem to be identical, i have since added a description of the byte values, the position can be found in the source or the annotated capture. The windows only actions aren't handled by windows but rely on the official software to be running in the background, therefore i wouldn't bother implementing them (unless someone wants them).

If i understand it correctly, most settings did work, however in the recent versions of the M711 backend changing the scrollspeed, DPI, button mapping and USB poll/report rate were disabled due to a lack of information. I have enabled the generic implementation of all settings in the M711 backend in 40f42ad0ef56b45edf831057d3d5c75ac8a76100, if you @rolimans or @nwildner were to confirm that changing (some of) these settings works now, i would update the documentation accordingly.

Feb 08 '21 22:02 dokutan

Ok. Maybe i'm stupid(and if i'm being, dont be afraid to tell me..lol) but i've tried to change simple things on my config file to test led colors, and setting them for each profile. Example:

[profile1]

# LED settings
color=ff0000
brightness=2
speed=0
lightmode=on
report_rate=500
--snip--

[profile2]

# LED settings
color=00ff00
brightness=2
speed=2
#lightmode=wave
lightmode=on
report_rate=500

So, profile 1 is red, while profile 2 is blue(should be green). Both profiles change the led color to white 5 seconds right after i execute something like sudo mouse_m908 -c mouse.ini -p 1

Feb 09 '21 02:02 nwildner

That means that sending the settings to the mouse works (white is the default value for this software) but there is a bug in the preparation of the data packet (the offsets for the color, brightness and LED speed were wrong), that should be fixed in 040c40141b808dc99eb16c9dba7346de2b2630a9.

PS @nwildner: I just noticed your fork with the PKBUILD is gone (i am using Arch myself and was therefore interested), are there any problems?

May 31 '21 11:05 zoeleu

There are four main aspects that need varying levels of effort. For the most part it boils down to trying various settings and checking if the results match as a big part of the model specific code has already been written. From my experience i can strongly recommend that you have the official software and a second input device available before trying to change the settings on the mouse (see https://github.com/dokutan/mouse_m908#safety).

I currently do not know if the LED related settings (lightmode, brightness, color, speed) can be read and changed correctly. To confirm this check if the output of mouse_m908 -R - is correct and try changing these settings to a few different values.
The same is true for the button mapping, however due to the differences between the mice there are three types of failure that could occur:
- The number of buttons assumed by this software is wrong
- The buttons are swapped, e.g. button_left is interpreted as button_right
- The buttons are labeled incorrectly
To check the macros use the same procedure. Please note that some mice have less than 15 macros available. Edit: the unkown ff ff 0 could simply mean that these bytes are for some reason stored as a macro. As long as changing and then reading macro8 works i see no real problem.
To address the DPI values, the hex values you see is part of the raw bytecode sent by/to the mouse and map to actual human-readable DPI values. Unfortunately these mappings vary between mice and follow no known pattern that is reasonably usable, therefore to be able to use the actual DPI values you would need to use the official software to set each of the available values, then look at the output from mouse_m908 for the matching hex values. Given that information it is relatively trivial to fix this issue.

If anything doesn't work as it should, please attach the config that you used and the output of mouse_m908 -R - and mouse_m908 -D -. Telling me that something works is equally valuable because i can then update the README.md.

Jun 01 '21 17:06 zoeleu

isn't it weird that 100dpi = 0x0200? 200dpi = 0x400?

Jun 01 '21 17:06 zoeleu

Found a pattern (I think?)

Yes, these values follow a basic pattern (here are the values from the M908, and for the M719):

if the DPI value is increased by 100 the first byte gets increased by 2 or 3
at some point for larger DPI, the step size between valid values changes from 100 to 200 and the second byte gets changed from 0 to 1 (the whole DPI value could be seen as a little-endian word, but this change doesn't happen at 0xff 0x00)

However, because the difference between adjacent values varies and the point at which the step size changes is different for each mouse i don't see a way around trying out at least the majority of DPI values. Additionally the minimum and maximum DPI (and therefore the amount of valid values) vary between mice.

isn't it weird that 100dpi = 0x0200? 200dpi = 0x400?

I personally wouldn't interpret these values as anything but arbitrary keys for a map, therefore no.

Edit: i have added initial support for actual DPI values (100-500) in 74d64a2dc4c60d9d30996a3e7382eb959461807d.

I didn't figure out how to use it, now my mouse doesn't move vertically. Would you help me?

Sep 15 '21 02:09 LeonardHM

@LeonardHM I suggest you try out the official software to fix your mouse. To debug this program it would be helpful if you could provide the config you used, the output of mouse_m908 -R - and mouse_m908 -D -, the version (which release or did you build from the master branch?) and if all profiles and DPI levels are affected.

I probably did something wrong

Sorry that i am only replying now, as far as i can tell you did absolutely nothing wrong.

After having a look at the data you provided i see no obvious cause for this issue, i suspect it might be caused by accidentally setting the DPI in the vertical direction to 0. To implement a proper fix would require capturing the usb communication with the official software when changing the DPI, have a look at this previous comment for details. If that is not possible i might be able to figure something out if you reset the mouse with the official software and then attach the output of running:

mouse_m908 -D -
mouse_m908 -R config.ini
mouse_m908 -c config.ini
mouse_m908 -D -

I used the two redragon programs for this model and it didn't work. I think the only way is trying to modify your code

Sep 17 '21 21:09 LeonardHM

I think the only way is trying to modify your code

That might be true, however there are two problems with that approach:

That even the official software is broken makes it look like a bug in the firmware to me, which could mean that even knowing what exactly to modify would not lead to success.
I don't have a clue which commands to modify without a capture of the data sent by official software.

I managed to reset. What do you need to try to fix the code?

Sep 30 '21 23:09 LeonardHM

What do you need to try to fix the code?

To get started with the main issue: a capture of applying the default settings with the official software. Additionally a second capture where you change a single DPI value and a screenshot showing the settings would be helpful.

I managed to reset.

I am genuinely curious how, if you could give me a brief description i would add it to the README.md in case someone else encounters a similar problem.

Oct 01 '21 21:10 dokutan

How do I capture? I clone the repository, and do "mouse_m908 -R -" and "mouse_m908 -D -" ?

To reset, it was (simply) using the official program this but on Windows 10. On 7 it didn't work, maybe due to machine problem or incompatibility, I don't know.

Oct 01 '21 21:10 LeonardHM

How do I capture?

You can use wireshark, here are a few links copied from a previous reply: https://bytepunk.wordpress.com/2017/03/25/reverse-engineering-a-usb-mouse/ https://github.com/pez2001/razer_chroma_drivers/wiki/Reverse-Engineering-USB-Protocol https://github.com/dokutan/rgb_keyboard/tree/master/doc

Please ask if anything remains unclear.

Oct 01 '21 21:10 dokutan

Wow. This sounds a little complicated. But I found some tutorials in my language, I will learn a little and do it soon. Is there any place we can get in touch? I believe that it is getting very polluted here and it will make it difficult for anyone to access looking for information

Oct 01 '21 22:10 LeonardHM

Sure, just send me an email at dokutan <at> tutanota <dot> com

Hello, I have a 711-FPS with the same issue - I think the simplest fix for now is implenting the "Link XY" feature that sets the DPI to be the same for both axes. I am currently generating a packet capture with Link XY on and off for this mouse.

Oct 06 '21 22:10 rasmysamy

m711-pcap.zip

The above file contains two packet captures. The first is applying the default settings (I had previously reset to default, this is applying after that). It's called linkxy-default.

The second file is a packet capture with the exact same settings but "Link XY" disabled.

Link XY makes it so that the X-dpi is assigned to the Y axis too.

Oct 06 '21 22:10 rasmysamy

@rasmysamy Thanks, as it turns out there isn't even a difference between the captures. Where other mice use two bytes for the DPI the M711 uses four, i.e. two bytes per axis. The problem was that the last two bytes were always set to 0 by this software.

I have implemented a simple fix (setting y-dpi = x-dpi = dpi) in 3d684797c080c6aa33118b91391211dad12a0503, and experimental support for different x- and y-dpi in https://github.com/dokutan/mouse_m908/tree/m711-xy-dpi. ~~I would merge that when someone confirms that it works.~~ Merged, the build works and at least it will get tested now.

Oct 07 '21 16:10 dokutan

@dokutan I'll be able to test the fix today or tomorrow, assuming the build works without an issue. Thanks, and have a nice day!

Hello. I have the Redragon M711 Cobra mouse and have captured some packets while using the mouse and applying a few settings in the official software. Should i send them here or open a new Issue?

Nov 13 '21 09:11 spflaumer

@1nekomata Feel free to post them here.

Nov 15 '21 16:11 dokutan

@dokutan Sorry for the late reply. Here is the file

Nov 19 '21 21:11 spflaumer

Let me know if you would need something else

Nov 19 '21 22:11 spflaumer

@1nekomata The most useful thing would be to try out as many features as possible, all features are implemented in some form but are not tested. Even reporting that a feature works as expected is useful, as that would allow me to update the readme.

Nov 22 '21 18:11 dokutan

Ok, i'll do that tomorrow

Nov 23 '21 18:11 spflaumer

@dokutan Can you tell me what i should try applying?

Nov 24 '21 19:11 spflaumer

@1nekomata You can use the example config and then set arbitrary values for the individual settings. Only when something doesn't work the values you used become interesting.

Nov 24 '21 19:11 dokutan

@dokutan i'll start with dpi then. 0200 is 100 dpi 0400 is 200 dpi and so on right?

Nov 24 '21 19:11 spflaumer

my config coming from windows

Nov 24 '21 19:11 spflaumer

@dokutan i applied this. color works, dpi works, need to remap a few buttons (dpi cycle is mapped to page back, change color mode isn't mapped, page forward isn't mapped, dpi lower isn't mapped) and applying polling rate works

@dokutan I'm gonna continue tomorrow and will send a config with all keys mapped properly and all color modes tested

Nov 24 '21 20:11 spflaumer

so far static and wave color mode works fine.

Nov 24 '21 20:11 spflaumer

@dokutan applying dpi works. disabling dpi modes works too. changing dpi works too. all color modes (seem to) work. only buttons that are not working are these 1 ~~isn't working~~ and 2 are working~~aren't working in firefox but work in gallery~~, ~~2 cycles dpi (should be backwards)~~, 3 switches dpi up (works normally), 4 ~~isn't working (should be dpi down)~~ is the same key as 1 (output of xev), samekey 5 works normally~~is backwards~~ ~~swapped with 2 and is now dpi-cycle (should be cycle color mode)~~

Nov 25 '21 13:11 spflaumer

@dokutan we don't have enough keys to be mapped to the mouse (8 vs 9) so the key i marked as 4 in the image above is the same key as the key i marked as 1

Nov 25 '21 13:11 spflaumer

@dokutan here is the pcap of button1 and button4 getting pressed once (note: apply display filter usb.bus_id == 1 && usb.device_address == 6)

Nov 25 '21 14:11 spflaumer

@1nekomata Thanks, your information and captured data proved to be quite useful. I have added support for remapping all buttons in f04a4cc5207788c4c6679f7e67f054275fb0067c. The example has been updated with a full list of buttons so you can try it out easily.

If that works correctly, the only missing info is the mapping between actual DPI values and the raw bytes. To get that you can set the DPI using the official software, then run mouse_m908 -R - and repeat the process until you have covered all possible values (100-500 are already known and can be skipped). If the button mapping doesn't work i would have another look at that.

Nov 25 '21 19:11 dokutan

ok i will do that. i am setting up a VM and am gonna do that ASAP

Nov 25 '21 19:11 spflaumer

@dokutan dpi1=0x0d000000 = dpi 600 dpi2=0x0f000000 = dpi 700 dpi3=0x12000000 = dpi 800 dpi4=0x14000000 = dpi 900 dpi5=0x16000000 = dpi 1000 sadly i haven't found a way to refresh RDCfg on Windows to see what dpi i just applied on linux

Nov 27 '21 15:11 spflaumer

@dokutan would mouse_m908 work on Win10?

Nov 27 '21 15:11 spflaumer

@dokutan all mouse buttons work as expected now thanks a lot!

Nov 27 '21 16:11 spflaumer

@1nekomata Thanks for the DPI mapping (edit: added in 0da955ef178308c4cf9d8c44abb2be4ff6750760). The known values are identical to the M908, if you can tell me the maximum supported DPI i could copy at least some values from the M908.

all mouse buttons work as expected now thanks a lot!

Perfect, that leaves only reading the button mapping from the mouse to be implemented. Could you capture the communication when opening RDCfg for the first time or connecting the mouse with RDCfg running for that?

sadly i haven't found a way to refresh RDCfg on Windows to see what dpi i just applied on linux

If i understand you correctly, you are setting the DPI on linux woth mouse_m908, then get the actual value with RDCfg on wondows. Doing the reverse (setting woth RDCfg, checking with mouse_m908) might be easier.

would mouse_m908 work on Win10?

There is no obvious reason it wouldn't work since all dependencies (libusb, c++ compile, make or cmake) should be available on windows as well.

yes, hang on a sec

no, i'm actually trying to have RDCfg detect what dpi has been set using mouse_m908 in order to check if those values are actually correct

Nov 27 '21 16:11 spflaumer

Also i cant seem to be able to apply dpi1=0x0d000000 dpi2=0x0f000000 dpi3=0x12000000 dpi4=0x14000000 dpi5=0x16000000 but i can apply dpi1=0x0d00 dpi2=0x0f00 dpi3=0x1200 dpi4=0x1400 dpi5=0x1600

Nov 27 '21 16:11 spflaumer

@dokutan dpi4=0x73000000 = dpi 5000 dpi5=0x73010000 = dpi 10000 (note: dpi 5000 and onwards is only in 200 increments instead of the usual 100)

Nov 27 '21 16:11 spflaumer

What about e.g. X100Y200 ? Also make sure the build you are using is based on the latest commit by running

git clone https://github.com/dokutan/mouse_m908
cd mouse_m908
# or
git pull

make clean
make # or make -j <number of threads>
sudo make install

Nov 27 '21 16:11 dokutan

What about e.g. X100Y200 ?

dunno gonna try now

Also make sure the build you are using is based on the latest commit by running

yes i am

Nov 27 '21 20:11 dokutan

@dokutan ok, everything seems to be working now

Nov 29 '21 18:11 spflaumer

i'm gonna test color, light modes, key mapping and applying dpi

Nov 29 '21 18:11 spflaumer

@dokutan here is what works color: breathing works breathing_rainbow works rainbow works static works wave works alternating works reactive works reactive_button works flashing works off works random works

led color works led brightness level works brightness works led animation speed works (1 = fastest 8=slowest)

scrollspeed works

dpi: dpi1_enable works dpi2_enable works dpi3_enable works dpi4_enable works dpi5_enable works

dpi1 works dpi2 works dpi3 works dpi4 works dpi5 works dpi range 0x0200 - 0x7301 (only M711 cobra; M711-FPS needs testing for 24000 dpi as M711 cobra only goes up to 10k) (X100Y200 works but i can't go higher than X1000Y1000; M711 cobra can't use different dpi on X and Y so it applies value of X always) report_rate works

key mapping: button_left works button_right works button_middle works button_backward works button_forward works button_dpi_up works button_dpi_down works button_lightmode works scroll_up works scroll_down works (note: i didn't test every button as it would take a lot of time)

Nov 29 '21 19:11 spflaumer

i think you can change status to "complete"

Nov 29 '21 19:11 spflaumer

i think you can change status to "complete"

Almost, two minor things are still missing for complete support:

You mentioned the M711 supports DPI up to 10k which corresponds to 0x7301. In the data i have 0x7301 corresponds to 10200. You can find the mapping table here if it helps: https://github.com/dokutan/mouse_m908/blob/a7387de00ca6b59cc609c9155c8b5b1d080c795b/include/m711/data.cpp#L45
Reading the button mapping is not implemented, should be easy to do but i need a capture of RDCfg getting the settings from the mouse by capturing at the initial start of RDCfg or connection of the mouse.

oh right i forgot to send you the .pcap!

Nov 29 '21 20:11 spflaumer

@dokutan here is opening RDCfg and applying settings

Nov 29 '21 20:11 spflaumer

@dokutan

You mentioned the M711 supports DPI up to 10k

only the M711 Cobra does. the M711-FPS can go up to 24k

Nov 29 '21 20:11 spflaumer

@1nekomata I have added the missing features in ded077560e4257264c28fb7e5b6669e9c7260546. Feel free to close the issue if everything works. Complete support for the M711-FPS should become a new issue.

Nov 30 '21 21:11 dokutan

@dokutan i can't exactly close it as i didn't open it. @rolimans was the one to open it

Nov 30 '21 21:11 spflaumer

@dokutan i'll double check tomorrow but afaik everything works. Thank you!

Nov 30 '21 21:11 spflaumer

@dokutan sorry for the late reply. i have tested all features that you added in https://github.com/dokutan/mouse_m908/commit/ded077560e4257264c28fb7e5b6669e9c7260546 and everything seems to be working just fine! i haven't tested macros yet though

Dec 02 '21 13:12 spflaumer

@dokutan macros are either not applied or are not captured by mouse_m908 --read / mouse_m908 -R -

Dec 02 '21 13:12 spflaumer

macros are either not applied or are not captured by mouse_m908 --read / mouse_m908 -R -

@1nekomata Could you figure that out by applying multiple macros with mouse_m908 and RDCfg? Some of the are other mice have buggy macros (only the first macro working, macros work but can't be read back, …), the same might be true for the M711.

Dec 02 '21 16:12 dokutan

@dokutan ok give me a sec

Dec 02 '21 17:12 spflaumer

@dokutan i can't seem to be able to read macros using mouse_m908 -R - . im gonna try to get a .pcap of the macro getting applied

Dec 02 '21 17:12 spflaumer

@dokutan here is a .pcap of me applying a macro with every single mouse action possible in RGCfg

Dec 02 '21 18:12 spflaumer

@1nekomata I can only guess the reason but the capture doesn't contain a macro, only the normal settings. Maybe binding the macro to a button is required for RDCfg to transfer it.

Have you tried setting a macro with mouse_m908 before?

Dec 04 '21 21:12 dokutan

@dokutan i did try. but afaik it didn't work as i couldn't confirm the macro worked nor could i read it with mouse_m908. i sadly can't test today anymore but i will try tomorrow
