Quick questions:

 - can you reproduce this with your friend's mouse (or any other
   mouse)?  If not, could your friend file a separate report so we can
   get to know his hardware?
 - please attach output from

	/usr/share/bug/linux-image-$(uname -r)/script 3>&1
 - please also test a recent kernel (3.x) from sid or experimental.  It
   should not require any other packages from sid except for
   linux-base and initramfs-tools.

If this is reproducible with a recent kernel, we should pass this
upstream (I guess that is linux-usb@vger.kernel.org, cc-ing Alan Stern
<stern@rowland.harvard.edu> and this bug log).  Otherwise, we can try
to find the fix and backport it.

Thanks,
Jonathan
