thank you again, paulo, for your off-list help. cam is now working nicely with xawtv, guvcview and skype. the colors slightly improved during day-light, when artificial light is used they still look bad though. i fiddled around with just about all v4l controls but couldn't really fix it. i'll run
Josef, white balance temperature and hue controls are being blacklisted in uvcvideo for all cameras due to a bug in the driver. A patch fixing the issue was committed recently (https://lists.berlios.de/pipermail/linux-uvc-devel/2009-December/005396.html) but I'm not sure when it will be available.

Hi, could you try the following: echo 2 /sys/module/uvcvideo/parameters/quirks this will set uvcvideo quirks to 2 or you can also try the latest uvcvideo: http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers please if you can, use the latest version
setting quirks to 2 unfortunately did not help. gucview's 1.2.1 output below [j...@darkstar ~]$ LC_ALL=C guvcview --verbose guvcview 1.2.1 unexpected integer value (1) for snd_numsec Strings must be quoted video_device: /dev/video0 vid_sleep: 0 cap_meth: 1 resolution: 640 x 480 windowsize: 480 x
You must reload the driver, rmmod uvcvideo modprobe uvcvideo otherwise the quirks want have any effect. uvcvideo is now mantained in the mercurial repo at linuxtv, installing v4l-dvb will also install uvcvideo, but if you want, just follow the instructions on the wiki to compile, but use: hg
