I have a Trust webcam and also a Trust headset (earphones and mic), both
work fine under windows.
In linux the webcam does not work, dmesg shows as below:

[ 11.717540] usb 1-7.3: Initialization succeeded
[ 11.717709] usb 1-7.3: V4L2 device registered as /dev/video0

[ 11.864015] intel8x0: clocking to 48000

I am also at a loss as to recoding with the mic
