Hi folks,
could anyone pls help me to get my Creative Webcam II started ?
The parport doesn't seem to find my camera.
Whats going wrong ?
And: Is the BIOS setting of the parallel port of any importance ?
I tried both ECP and ECP+EEP, (io=0x378, IRQ 7 set up in the BIOS),
both dont work but gives the same results,
as stated below.
Many thanks, Frank
My configuration:
I have a Pentium II, SuSE Linux 6.3, kernel updated to 2.2.17,
(it didnt work with 2.2.13 before either)
cpia 1.1 driver installed,
parport configured as module:
My current modules.conf:
...
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=none,none
...
When I load the modules, with:
modprobe parport
modprobe parport_pc dma=3 irq=7
modprobe videodev
insmod cpia
insmod cpia_pp parport=0
dmesg says:
parport0: PC-style at 0x378 (0x778), irq 7, dma 3

probably then its not astonishing that mcam doesnt find the camera ?
