Support for ID 1c88:1001 Somagic, Inc.
I've scoured the internet for a means to get this working in linux (Centos 7 flavor). I'd be willing to help in any way I can, just let me know what I can do!
Nice,
The source code for the accompanying tools are pulled from the debian project: https://github.com/stevelacy/EasyCap/tree/master/somagic-easycap-tools_1.1 https://github.com/stevelacy/EasyCap/tree/master/somagic-easycap_1.1 If you could compile the driver or determine if the debain driver works on fedora.
Did you manage to get the project, or part of it to run?
I was not able to successfully use the extraction tool on any of the SmiUsbGrabber3C.sys files, as each version failed, per OS (xp, win7, etc..) with "Somagic firmware was not found in driver file." I did test the extraction tool with the included SmiUsbGrabber.sys file, which successfully extracted. None of the file sizes matched in somagic-extract-firmware.c file. The xp version on my CD is 813617 (vs 805632 in the extraction tool).

Attached a usbmon dump of a few minutes. It includes both the device and the usb hub it was connected to, both on bus 001. usbmonzip.zip
I've got the same issue on Arch Linux. I'm happy to help, if you give me some direction...
I tried with the source from the old repo on Google Code, then with yours. I was unable to extract the firmware from the drivers that were provided from the ToOTMC (branded dongle) website.
I haven't used it in a while so I'd need to re-build as well. Let me see if I can extract the firmware for that device
Just as a note, multiple versions (for different windows versions) of the driver for this device which identifies as 1c88:1001 are here:
https://ftp.csl-computer.com/pub/drivers/videograbber/302591-USB_Video_Grabber/
Extract tool doesn't work for any of them though

Yeah, the signature for the driver changed when they changed the device id: https://github.com/stevelacy/EasyCap/blob/master/somagic-easycap-tools_1.1/somagic-extract-firmware.c#L205

Syntax error: redirection unexpected and Syntax error: "(" sound like bash errors. https://stackoverflow.com/a/2462357
Thank you!
I run
sudo dpkg-reconfigure dash
and select No. But now I have other error:
pi@raspberrypi:~/EasyCap/somagic-easycap_1.1 $ somagic-init
-bash: /usr/local/bin/somagic-init: cannot execute binary file: Exec format error
I suppose it's because of incompatibility with ARM. Where can you download the sources to compile it from Raspbian?
Regards
The source is in this repo, docs: https://github.com/stevelacy/EasyCap/blob/master/documentation/installation.md#compile-from-source
Thank you!
I just tried this:
cd EasyCap
make clean
make
sudo make install

Yes!, it's plugged to Raspberry Pi 2 and the green led is high, but my id is 1c88:1001 Somagic, Inc (aqprox brand).

Failed to set active device configuration: Device or resource busy
I added 1001 device to somagic-init and somagic-capture and then compile it but I get the same message.
sudo somagic-init
Failed to set active device configuration: Device or resource busy

Failed to set active device configuration: Device or resource busy
I have the same experience as @hexagon-robotics . I put my 1001 code into the somagic-init, but I get the same device or resource busy. I also think that the firmware distributed in the git repo is not for the 1001 device. (Generally, bad form to distribute built binaries in a git repo)
So, how does one go about decoding the .sys file to find the right firmware for the 0x1001 devices?
No, I will close this issue as I no longer am adding support for new devices I do not own
@stevelacy Surely there is still a possibility of others adding support, since this is an open source project? Might want to leave it open for others to see that this is still an issue.
Yes, I will gladly merge any PR for adding new devices, I'll keep it open for that
I have an EasyCap which identifies as 1c88:1001 and I also have the original driver CD however the firmware extract utility does not recognise any of the firmware files.
I am using a Raspberry Pi 4 running the latest Raspbian and I compiled the tools from source. Is thre anything I can do? If someone gives me instructions I can generate the CRC or whatever and push it to the repo. It would be great if I can get this thing working
Hi. I've managed to make firmware extraction work for 1c88:1001: see https://github.com/stevelacy/EasyCap/pull/13
However I couldn't make somagic-init work with it yet though. What I've tried:
- modify
somagic-initto support1c88:1001device identifier instead of1c88:0007 - release the device held by usbhid with
echo -n "2-1:1.0" > /sys/bus/usb/drivers/usbhid/unbind - run
somagic-init

^C
It seems that for this particular device (the Somagic 1c88:1001) you do not need the firmware nor to run somagic-init. The USB ID does not change at any time. The key is to release the device from the USB HID module using the line mentioned by hsyl20:
echo -n "2-1:1.0" > /sys/bus/usb/drivers/usbhid/unbind
I added the proper USB ID to somagic-capture.c, and the program manages to capture some video data after freeing the USB device and connecting a camera.
To decode it properly, I had to use a 720x480 image size for the raw video, which may have to do with the camera I was using. Mplayer could play it straight using the options given in the documentation.
Thus the device seems to work, but it is a matter or releasing the HID module from it before you can use the program.
Edit: Added the critical step of releasing the driver from the USB HID. Edit 2: I managed to decode it properly, added info.
Hi pablob127,
I added the correct USB ID to the source, but can seem to complete the step of releasing the device as I get this error:
~/source/EasyCap/somagic-easycap_1.1$ sudo echo -n "2-1:1.0" > /sys/bus/usb/drivers/usbhid/unbind bash: /sys/bus/usb/drivers/usbhid/unbind: Permission denied. Perhaps the echo string required is different than your example? Here's some additional information:

The redirection isn't done by root, hence the error. See: https://stackoverflow.com/questions/82256/how-do-i-use-sudo-to-redirect-output-to-a-location-i-dont-have-permission-to-wr
Moreover you need to adapt the device number (e.g. "2-1:1.0" above) to your device. First find the device id:

I have new EzCap USB Video Grabber from aliexpress (https://aliexpress.ru/item/32824460178.html). The CD with Windows driver is included. In Windows 8.1 device is works.
And faced with installation too. I use Slackware64-current linux up to date.

I dowloaded EasyCap source version 1.1 from github and compiled. Then applied somagic-easycap-tools_1.1 for copy of driver from CD.
$ sudo ./somagic-extract-firmware ../../Driver/Drivers/win_xp/SmiUsbGrabber3C.sys Firmware written to '/lib/firmware/somagic_firmware.bin'.
Unbind the device:
echo -n "1-1:1.1" > /sys/bus/usb/drivers/usbhid/unbind
Go to somagic-easycap_1.1 directory and apply somagic-init:
sudo ./somagic-init
Firmware file '/lib/firmware/somagic_firmware.bin' was not recognized.
Then I change ID in somagic-init.c to 0x1001, recompile and again
sudo ./somagic-init
Firmware file '/lib/firmware/somagic_firmware.bin' was not recognized.
However, video capture is works after reboot.
sudo ./somagic-capture | mplayer -vf yadif,screenshot -demuxer rawvideo -rawvideo "pal:format=uyvy:fps=25" -aspect 4:3 -
Also I changed raw to #define PRODUCT 0x1001 in somagic-audio-capture.c. And audio is captured
However, the last problem remains. How to capture video and audio together?
I try to use somagic-both:
sudo ./somagic-both 2> >(ffplay -f s32le -ar 48k -ac 2 -i -) | ffplay -f rawvideo -pixel_format uyvy422 -video_size 720x576 -framerate 25 -vf yadif -i -
I see video but no audio. somagic-audio-capture gives s32le PCM audio flow, I listen audio without video. I try to change PCM format to s16le, s24le, and many others, no effects. I listen noise or silent. Where the normal sound? What format of audio dataflow generated by somagic-both?
