[linux-uvc-devel] We can add LightCam 1020 to the list of supported devices

[h***@seznam.cz]

USB webcam Genius LightCam 1020 (0458:7091) tested successfuly on 2.6.32
mainline kernel.

Product: LightCam 1020
Manufacturer: KYE Systems Corp.
configuration #1 chosen from 1 choice
Linux video capture interface: v2.00
uvcvideo: Found UVC 1.00 device LightCam 1020 (0458:7091)

So far only limited testing in luvcview, mplayer and mencoder was possible.
The webcam switches its IR leds and its own IR-cut filter automatically by
means of its firmware in low light conditions. Both stills and video can be
captured. The MJPEG capture needs some tweaking (green output only), YUV {
[rawyuy2] vfm: raw (RAW YUY2) in mplayer} works out of the box.
