[Bug 622168] Re: webcam "device initialization failed" in lucid (needs high-speed USB 2.0 port) but has worked in past on lucid

[Kim Tyler]

After adding some packages yesterday to maverick (nvidia driver, compiz,
etc) and adding any updates, I rebooted again today into maverick, and
the webcam works!

Rebooted from cold, and webcam failed again.

I'll have a look at whether cold boot or reboot from different versions
of ubuntu cause problems.
