Sadly this last week I had to install Teams on Devuan as it did not pick up the Webcam as I am currently undertaking Mandarin Class via Teams. This meant quickly having to install Teams on Devuan which I didn't want to do as my experience is that it takes over the machine (even after removing it from startup applications!) Aaaaarrrrrrrggggghhhh!

lsusb in Konsole on the Host picks up the id and correctly identifies the device:

In Qemu Under USB connections I have:

I am aware that when using VB I had to change the USB settings toi 1.1 (shows how old the webcam is). Would I be better off upgrading the webcam  to a newer model?

Thanks.
