uvcvideo: Found UVC 1.00 device Slim 1322 AF (0458:704d)

Modul uvcvideo vyžaduje v jadre povolené (i ako modul) CONFIG_VIDEO_DEV = Video For Linux.
Nainštalovať modul jadra uvcvideo z jeho domovskej stránky (viď. odkaz hore), alebo zodpovedajúci z distribúcie. (v Gentoo je v portage ako media-video/linux-uvc)
Skontrolovať správnosť (malo by zobraziť obraz) napríklad cez:
$ luvcview -f yuv

lucview bez -f predpoklada format jpeg, a hlasi chybu:

Unable to set format: 22.
  Init v4L2 failed !! exit fatal

Jedna z mála webkameriek podporujúcich USB Video Class štandard, snáď jediná s takou nízkou cenou. Ako bonus, auto-focus.

V Ubuntu (8.10 i 9.04) funguje bez problemu out-of-the-box.
