Cannot Connect Web Cam

I’ve got a fresh copy of Unbutu Mate running in my laptop however I cannot get my Logitech Web Cam to work. It’s maybe a year old camera - C720 might be the model number IIRC.

If I type lsusb in a terminal window I can see the camera plugged in and detected. However nothing comes up in Cheese or Discord (where I want to use it).

Any help in fixing this would be great.

if command
lsmod | grep uvc
gives you a hit for uvcvideo then your cam is uvc compliant and the app
guvcview should work

if it works but you need Cheese or Discord for a particular purpose can you mention that need?

I need it to work it to work in my web browser mainly (via appear.in)

I’m still unable to get the web cam working.
