Веб-камера

Подарили мне Genius VideoCAM Trek.
Полазив по интернету нашел такую строчку: VideoCam Trek -> This cam uses the  Sonix SN9C101 chip

Действительно, модуль sn9c102 создает в /dev/v4l/video0:

sn9c102: V4L2 driver for SN9C10x PC Camera Controllers v1:1.24
usb 3-1: SN9C10[12] PC Camera Controller detected (vid/pid 0x0C45/0x6005)
usb 3-1: TAS5110C1B image sensor detected
usb 3-1: Initialization succeeded
usb 3-1: V4L2 device registered as /dev/video0
usb 3-1: Optional device control through 'sysfs' interface ready
usbcore: registered new driver sn9c102

По любые попытки получить картинку приводят к одному и тому же:
