Title:
Microsoft LifeCam Cinema reports "device descriptor read/all, error
-71" on 20.04 with USB-C adaptor
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have a MS LifeCam Cinema, which is known to work with Ubuntu in the
past, though forum posts show it no longer working as of ~18.04.
I recently went back to Ubuntu as an actual desktop OS with 20.04 on a
dell xps 13, which has a somewhat average webcam in the lid, so tried
out the lifecam. It failed to negotiate USB settings properly:
[622581.193592] usb 3-8: new high-speed USB device number 71 using xhci_hcd
[622581.342507] usb 3-8: device descriptor read/all, error -71

[622583.027700] usb 3-8: can't read configurations, error -71
[622583.027760] usb usb3-port8: unable to enumerate USB device
I suspect it needs some USB quirks applied, since the device works
perfectly fine on Windows still.
