First, did you hace the same problem in 11.10 (Oneiric)?
Can you run the command
lsmod | grep usb
in a terminal window and post its output?
The change we have done in terms of USB is mainly blacklisting the "usblp" kernel module, as for many users their problems went away when they blacklisted the module. We have also fixed a crash and did some missing variable initializations in the new USB backend.
This is not necessarily a fix for your problem, but we have asked also you for testing as it was a candidate.
To the SRU team: This bug turns out as not covered by this SRU. Removing verification tag.
