Welcome to the weird and wonderful world of Windows webcams in Linux!

With any luck you should be able to get your webcam to work.
Give it a try but do not waste too much time on it. If all else fails, you may find it simpler to sell your existing webcam and buy a cheap Logitech webcam that is Linux compatible.
Do make sure that you check the Linux user feedback on any webcam before purchase.
