Thanks for the reply.

Here is the output when it fails.  The "Unable to dequeue buffer: no
such device" message happens hundreds of times.

...
Oct 17 13:54:05 workstation1 plasmashell[16214]: V4L2_CORE:
(VIDIOC_DQBUF) Unable to dequeue buffer: No such device

There should have been some USB message before that started.

Oct 17 13:54:05 workstation1 kernel: usb 1-3: new high-speed USB
device number 10 using xhci_hcd

It's resetting for some reason.  Here it reconnects.

Oct 17 13:54:06 workstation1 kernel: usb 1-3: config 1 interface 0
altsetting 0 bulk endpoint 0x2 has invalid maxpacket 64

That's interesting and might be relevant.

Find the log lines before the dequeue errors start to see what happened.
