This is unlikely to be a regression between squeeze-backports
and wheezy, because they should be functionally the same
(aside from some ARM configurations).
What was the previous working kernel package version, as shown by
'dpkg -s linux-image-3.2.0-0.bpo.4-amd64' ?

This seems to indicate a problem (maybe a bug) in allocation of USB
bandwidth. Is this device connected directly to the USB port, or
through a hub?
