Which kernel is that?  You can get the kernel version from the
parenthesis in /proc/version.

Ok, let's start with that.

These might be two different problems: one related to power saving, and
the other related to large transfers.  Which would you like to start with?

No, since reasonably current kernels reproduce the trouble, we should
just get in touch with upstream.

Please test with 3.2.4-1 from sid and provide

 - full "dmesg" output from booting (as an attachment)
 - "lsusb -v" output (as another attachment)
 - "dmesg" output demonstrating what happens in the scenario you have
   chosen to focus on
 - steps to reproduce, and how reproducible this is (do the steps work
   100% of the time? 50% of the time?)
 - symptoms, how they differ from what you expected, and how that
   indicates a bug
 - any other background that might be helpful (other observations,
   what happened in other kernel versions, etc)
 - a link to this bug log for the full story

to linux-usb@vger.kernel.org, cc-ing Sarah Sharp
<sarah.a.sharp@linux.intel.com> and either me or this bug log so we
can track it.

Thanks.
