Yay.

Ok, one more test and then we should take this upstream: if you set
the usbcore.autosuspend parameter to -1, does that change anything?

	# modprobe -r ehci_hcd; # or unplug mouse
	# echo -1 >/sys/module/usbcore/parameters/autosuspend
	# modprobe ehci_hcd; # or replace mouse

Either way, please send a summary to linux-usb@vger.kernel.org, cc-ing
Alan Stern <stern@rowland.harvard.edu>, linux-input@vger.kernel.org,
and either me or this bug log so we can track it.  Be sure to mention:

 - steps to reproduce, expected result, actual result, and how the
   difference indicates a bug (should be simple enough)

 - which kernels you have tested and what happened with each

 - how reproducible it is and how long it takes (e.g., within a couple
   of hours 80% of the time?)

 - full "dmesg" output from booting and reproducing it, as an
   attachment or link

 - a link to http://bugs.debian.org/689368 for the backstory

 - any other weird symptoms or observations

If we're lucky, someone upstream will have ideas for commands or
patches to try to further track down the cause.

Thanks again for your help and patience.

Good luck,
Jonathan
