I just noticed this... After mounting the cam and executing the cp command,
the computers load keeps mounting, even though nothing visible is happening.
No swap usage, no cpu usage, memory stays the same...

It's mounted from 0.2 to 11.9 in under 2 minutes now. I don't notice
anything...

I've also activated the usb-storage verbose mode, and i'll append the new
info here (the point where it hangs)

The following message is also seen in /var/log/syslog:

Nov 15 19:13:28 whocares kernel: usb-uhci.c: ENXIO 80000280, flags 0, urb
db7aad40, burb db7aac40

a LOT.

Thanks again

DK
