Hi Greg,
It appears while debugging camserv to add some features, if I kill camserv
prematurely, and try to unload the pwc driver I am unable to.
I get the following:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1068 root 20 -5 0 0 0 R 95.8 0.0 3:26.84 khubd
The kernel USB hub daemon goes nuts.
If I disconnect the cam from the USB
[4294920.159000] pwc pwc_isoc_handler() called with status -84 [CRC/Timeout
(could be anything)].

What information do you need? Yes I know it's bad to yank out USB devices that
aren't properly shut down.
Thanks,
Shawn.
