Hm, no softlockups this time.  Weird.

Is this a regression (in other words, did any earlier kernel version
work better)?  The 2.6.32.y-based kernel in squeeze should work fine
on a wheezy/sid system if you want to try it.

Please report this to linux-usb@vger.kernel.org, cc-ing either me or this
bug log so we can track it.  Be sure to mention:

 - steps to reproduce the problem, expected result, actual result, and
   how the difference indicates a bug
 - how reproducible it is and how long it takes to reproduce (e.g. 80%
   of the time after 1 hour?)
 - which kernel versions you have tested and what happened with each
 - full "dmesg" output from booting and reproducing the bug, as an
   attachment or a link
 - what kind of debugging help you will be able to provide (e.g., if
   someone provides a patch to try, can you test it?)
 - any other weird observations or workarounds
 - a link to http://bugs.debian.org/674164 for the backstory

Hopefully someone upstream will have ideas for tracking it down
further.

Thanks and hope that helps,
Jonathan
