A button doubles as Start button press

I haven't been able to see the effects in evtest yet:

But in EmulationStation and RetroArch, every A button press on the controller was triggering the A action and Start button press action. I'm going to reboot and see if that fixes it, but how should I debug this? It happened all of a sudden after 48-72 hours of connected use.

[johnjelinek]

weird, after a reboot. It didn't show up in evtest again. I'm trying to re-install.

[johnjelinek]

hmm, re-install didn't fix it either. I don't know how to get it to show back up:

[cvuchener]

It looks like the controller is not connected. Is the light on or did it fail to connect?

[johnjelinek]

The light is on, and it did connect because you still see it in lsusb and evtest (event2)

[johnjelinek]

I made the light turn off and back on, but still no worky.

[johnjelinek]

I think you're right though, it must not be connecting. When I turn it off, I see the same output from the commands above.

[johnjelinek]

I don't know how to get it to re-connect. I've unplugged and re-plugged the wireless usb connections, no progress.

[cvuchener]

If you start usbmon when trying to connect, is there any output? Does it work if you use a wired connection?

[johnjelinek]

hmm ... usbmon seems to not be recommended for raspberry pi: https://www.raspberrypi.org/forums/viewtopic.php?t=26180&p=238972

[johnjelinek]

the device also does not show up when I plug in.

I see nothing against using usbmon on raspberry pi in that link. It is against using usbmon for reading keyboard inputs and I agree with that but here we want to debug usb and it is usbmon intended use. Although I would recommend to use the usbmon command that read the binary /dev/usbmonN files instead of the direct text interface.

the device also does not show up when I plug in.

Nothing special in the logs?

In the dmesg command earlier you used grep Valve. grep is case sensitive you may have missed some messages. Use grep valve-sc or grep -i valve.

[johnjelinek]

I don't have a usbmon command, so I'm rebuilding the kernel to see if that's something I can get. However, when I switch to the userland driver, the controller works as expected, so I don't think the problem is with a disconnection.
