-----Original Message-----
From: Andrew Burgess [mailto:aab@cichlid.com]
it sounds like a bug recently tracked down on the usb devel list
(search for 'Failed to resubmit video URB')
it turned out to be a bug in the usb host controller; if you
do an lspci do you see anything made by NetMos or MosChip?

Hi,
Running kernel 3.2 for 12+ hours, no issues yet, will update thread if any further issues occur.
Justin.
