USRP B205 mini-i Compatibility

[jasmitch]

Have a USRP B205 connected by USB and SigDigger(AppImage) detects the device however reports it as being unavailable? I get this message from the application log: "Referenced device `uhd (B205mini 313634B)' is not available. device suscan_source_detect_devices"

I get the following output from the command line:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown

Okay, this is odd. Does your USRP work with other applications?

[jasmitch]

Yeah, it is working fine with gqrx, sdrangel & general USRP utilities.

When you say it detects the device, but it is not available, where do you see this? In the device window? Or in the configuration dialog? (in which you get to choose the appropriate device) What happens when you click Refresh in the device window?

[jasmitch]

I get that from the message log(cntrl+l): "Referenced device `uhd (B205mini 313634B)' is not available. device suscan_source_detect_devices"

When I look at the device windows(cntrl+d), I can see the device but it is greyed out. Pressing the refresh button doesn't change anything.

[BatchDrake]

Interesting. Could you do the following?

1. Find the files ~/.suscan/config/uiconfig.yaml and ~/.suscan/config/sources.yaml and attach them to this issue (so I can rule out any misconfiguration due to wrong IPs or whatever).
2. Open a terminal window, go to wherever your AppImage is, and softlink it to a file named suscli (and make sure that it is executable). If your AppImage file is named SigDigger-0.3.0-x86_64-full.AppImage, you just would need to do:

$ ln -s SigDigger-0.3.0-x86_64-full.AppImage suscli
$ chmod a+x suscli

3. In that same directory, run ./suscli devices. You should see something like this:

$ ./suscli devices
... (lots of debug logs) ...

 ndx Device name                              Driver   Interface Availability 
------------------------------------------------------------------------------
[ 0] Dummy device                             null     local     unavailable
[ 1] ... (whatever devices you have plugged) ...

If I don't find the error here, the next step will be to provide you with an engineering build so we can debug this issue (sounds scary but it is not, it would consist of another SigDigger AppImage that prints more logs and lets you do more tests).

I'm currently running Ubuntu 20.04.5 LTS, was thinking of performing a fresh install of 22.04.01 LTS and re-installing the USRP mini driver with relevant packages and trying the AppImage again?

Would it be better to compile SigDigger from source?

[BatchDrake]

Hey,

Some people are experiencing issues with the USRP as well (especially the x300 ones), but every clue so far is pointing to driver issues.

Nonetheless, if building is an option for you, yes. Please go ahead, so we can rule out more possible causes. My suggestion is that you download & execute https://actinid.org/blsd. Is a script that automatizes the process of cloning & building SigDigger from the development branch. The cool thing is that you do not need root for this, everything is going to be compiled in a subdirectory, and you can run SigDigger directly from there.

[jasmitch]

Performed a fresh install of 22.04.01 LTS and installed SigDigger via the dev branch build script at https://actinid.org/blsd. Can now see the device with this new build and looks to be working fine, thanks for your help.

[BatchDrake]

Thanks to you! I will link this thread to other users that seem to be affected by the same issue.
