I am running Ubuntu 20.04.1 LTS. I have my webcam operational here:
$ v4l2-ctl –list-devices
Logitech BRIO (usb-0000:08:00.0-2):
Under my Windows 10 guest, this webcam is not visible at all. Some of my other USB devices are. I have the guest’s settings set to support USB 3.1. The cam is plugged into a USB3 socket.
I use the cam for Zoom. Is there something I may be missing? With Windows 10 as a host, the cam was visible and usable without issue. I copied the same guest configuration that I originally used under Windows 10.
