-----Original Message-----
From: Andrew Burgess [mailto:aab@...hlid.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?

mine says:

0b:00.0 USB Controller: NetMos Technology MCS9990 PCIe to 4‐Port USB  
2.0 Host Controller

mine is a pcie card; perhaps you have one built in?

It’s a bit different for my model:
