It is not a big thing, just confusing me sometimes. (LED's on ... Cam on,
LED's off, Cam off, you know what I mean?
pwc accepts the params from modporbe without any error, but nothing
happens....

OK, here ist the modprobe output:
linux:/home/bernd # modprobe pwc trace=65535
FATAL: Error inserting pwc --> I've also tried
trace=0..10, same result
(/lib/modules/2.6.13-15.8-default/kernel/drivers/usb/media/pwc.ko): Unknown
symbol in module, or unknown parameter (see dmesg)
dmesg:
Mar 27 19:34:52 linux kernel: pwc: module not supported by Novell, setting U
taint flag.
Mar 27 19:34:52 linux kernel: pwc: Unknown parameter `trace'
same with insmod:
linux:/home/bernd #
insmod /lib/modules/2.6.13-15.8-default/kernel/drivers/usb/media/pwc.ko trace
65535
insmod: error inserting
'/lib/modules/2.6.13-15.8-default/kernel/drivers/usb/media/pwc.ko': -1
Unknown symbol in module
dmesg:
Mar 27 19:50:07 linux kernel: pwc: module not supported by Novell, setting U
taint flag.
Mar 27 19:50:07 linux kernel: pwc: Unknown parameter `trace'

I really would like to debug that, but ;-) I probably need the 'trace'

I appreciate your comments.
Bernd
