XHCI unplug of USB-C device is not detected

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



My only USB-C device is a Logitech StreamCam, which seems to cause some 
kind of lock on resources when unplugged.

The symptom is it works when first plugged in to a PC. But after 
unplugging it can't be made to work again.

I don't have prior experience of these components. I enabled debug 
messages:

  echo -n "module xhci_hcd =p" > /sys/kernel/debug/dynamic_debug/control

Plugging in the webcam produces the dmesg below.

But unplugging simply results in no activity -- zero output in dmesg. Same 
when plugging in again.

After unplugging the device is still listed:

  $ lsusb

and the associated uvcvideo module is free and can be removed with rmmod:

  $ lsmod | grep uvcvideo
  uvcvideo              110592  0
  videobuf2_vmalloc      20480  1 uvcvideo
  videobuf2_v4l2         28672  1 uvcvideo
  videobuf2_common       45056  4 videobuf2_vmalloc,videobuf2_v4l2,uvcvideo,videobuf2_memops
  videodev              200704  3 videobuf2_v4l2,uvcvideo,videobuf2_common
  mc                     53248  5 videodev,snd_usb_audio,videobuf2_v4l2,uvcvideo,videobuf2_common

The USB subsystem isn't entirely locked up. A USB keyboard on a different 
type A port is picked up as expected.

I have access to a Thinkpad X230 laptop (Alpine Linux; kernel 
5.10.61-0-lts), and everything works as expected.

So it seems to be specific to the PC hardware (Gigabyte H170-D3HP 
motherboard -- a single USB-C port and several regular ones). Or perhaps 
even the kernel config.

What debugging can I do next?

Thanks
