Hi, The problem was that each webcam application reported :no space left on device. After some experiments I found out that camera works when "Bus 002 Device 006: ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter" is unplugged. It seems that this bluetooth adapter reserves too much bandwidth. Quite strange as bluetooth does not usually need too much bandwith. What to do next ?
