Hi. I have 2 of these c310 Logitech webcams and they both have the same problem. I'm running windows 10 on a desktop pc. Both cams worked for a good long time, and then they stopped. I took both apart and reassembled and they worked for a while, but then they both stopped. I took the cam to a repair person just to get a clue on how to go on, and he got it working, so maybe it's not a hardware issue. I've deleted and reinstalled the correct drivers. Yesterday, I thought perhaps my Eset virus control software was interfering so I fiddled with that a bit and got it working, but then this morning again it wouldn't work. I tried the things I was fiddling with in Eset last night, but it wouldn't work. Very mystifying. Thanks for any help.
