Ahoj,
koupil jsem si uvedenou webkameru, odzkoušel na stolním PC (debian Wheezy) vše okamžitě fungovalo (plug and play).
Ovšem na Raspbianu mi nefunguje. Můžete mi prosím poradit??

Pokud zkusím přehrát video ve vlc, píše chybu:
ALSA lib pcm.c:7339:(snd_pcm_recover) overrun occurred
Při použití programu motion mi to psalo, že kamera je zaneprázdněná, podle návodu navod jsem zakomentoval některé řádky v /lib/udev/rules.d/60-persistent-v4l.rules, tuto chybu už to nepíše ale zase nefunguje(změnu jsem vrátil zpět).
A nakonec přehrátí pomocí mplayeru ukazuje zelenou obrazovku...
s tímto výstupem:

[VO_XV] It seems there is no Xvideo support for your video card available.
[VO_XV] Run 'xvinfo' to verify its Xv support and read
