I got an webcam fom Medion (E86002) with builtin Mic.
When plugged in, I installed a camerafunsoftware from the gmarket. i was able to make photos and also it was able to cam.
So I installed skype and tried to connect to a friend, but there was only his voice.
I couldn´t see him - also I had a black conrolpicture of what my cam is showing.
In fact, it seems to be a little step to make it work. where is skype expecting to find the camera, the camerafunsoftware found. Maybe it just needs a link.
So go for it! that would be another big step!
