ze stranek
http://qce-ga.sourceforge.net/
stahnout driver a prelozit oproti kernelu.
Dal prelozit podporu pro video4linux a usb-uhci (ohci)
prelozit xawtv a jedeme :)

takze nakonec museji byt moduly
mod_quickcam           38160   1
videodev                3968   2  [mod_quickcam]
usb-uhci

Ovladace nejde prelozit proti jadru 2.4.20, jelikoz byl trochu pozmenen USB subsystem. Takze je potreba trochu upravit zdrojaky qce-ga-0.40c:

sed 's/urb_t/struct urb/' <quickcam.c >quickcam.c2
mv quickcam.c2 quickcam.c
sed 's/urb_t/struct urb/' <quickcam.h >quickcam.h2
mv quickcam.h2 quickcam.h

nekupovat - kdyz ji dostanete, je to skoro za trest

kvalita je opravdu hrozna
