Dear all,

(please Cc)

I see quite some discussion here about hanging USB controls from
Renesas. Interestingly, I see the very same behaviour with my Intel USB
controller:
00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31)

It happens again and again that:
Nov 12 10:57:58 bulldog kernel: xhci_hcd 0000:00:14.0: Abort failed to stop command ring: -110
Nov 12 10:57:58 bulldog kernel: xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead
Nov 12 10:57:58 bulldog kernel: xhci_hcd 0000:00:14.0: HC died; cleaning up
Nov 12 10:57:58 bulldog kernel: xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command

and I loose all mouse/kbd access.

I have the feeling that it happens more often/at all when I redirect my
USB webcam to a virtual machine using virt-manager.
Before the above happened, the log showed
Nov 12 10:57:06 bulldog kernel: usb 1-12: reset high-speed USB device number 47 using xhci_hcd
Nov 12 10:57:11 bulldog kernel: usb 1-12: device descriptor read/64, error -110
Nov 12 10:57:27 bulldog kernel: usb 1-12: device descriptor read/64, error -110
Nov 12 10:57:27 bulldog kernel: usb 1-12: reset high-speed USB device number 47 using xhci_hcd
Nov 12 10:57:32 bulldog kernel: usb 1-12: device descriptor read/64, error -110
Nov 12 10:57:48 bulldog kernel: usb 1-12: device descriptor read/64, error -110
Nov 12 10:57:48 bulldog kernel: usb 1-12: reset high-speed USB device number 47 using xhci_hcd

where 
HD Pro Webcam C920 as /devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12:1.0/input/input40

I am currently running 5.15.1.

Is there anything (besides ssh-ing into the machine and unbind/bind the
pci device) I can provide or do?

Thanks

Norbert
