Subject: Problem pwc-10.0.12-rc1 oops
Hallo *!
Problem:
- after approximately 6h breaks motion/pwc.
(s. dmesg)
- The installation makes with following guidance:
http://www.seismo.ethz.ch/linux/webcam.html
CONFIG_USB_PWC=m
and overwrite module with version pwc-10.0.12-rc1
- not possibly the module to removed
(s. rmmod)
- the pwc-modul (shipped with linux-2.6.16) does not work.
xawtv say: no way to get: 384x288 32 bit TrueColor (LE: bgr-)
Whats going wrong?
regards Torsten
