mplogas - Support Thread for container(s)

Quick little pro-tip for forum posterity.

 

I force updated the LaaC image today because I was doing some system maintenance (don't ask, I didn't need to do it, but I did), and afterward I was getting this error in the LaaC docker log on container start:

 

ERROR: no device matches available drivers and selection criteria

 

Thinking I messed the image up, I deleted my template and reinstalled from Community Apps, though I was met with the same error. The device was still recognized on the host in the /sys/bus/usb/devices/X-Y and /dev/bus/usb/XXX/YYY locations (I use the former in my template) so it wasn't an availability issue. On a lark, I thought that the device might not have been let go correctly by docker when I force updated the image and the device is now bound to an invalid endpoint (or something like that). So I stopped the running LaaC container, and ran these commands in a su terminal:

 

echo 'X-Y' | tee /sys/bus/usb/drivers/usb/unbind
echo 'X-Y' | tee /sys/bus/usb/drivers/usb/bind

 

Upon restarting the LaaC container, my Corsair Commander was once again able to be seen by liquidctl.

 

Hope this helps someone in the future!
