OK.  The patch isn't expected to solve the problem completely.  
The Linux USB developers would like to be cc'ed on any future bug
reports.

You can edit the Makefile and append something to the EXTRAVERSION.
Then, after applying the patch, check for rejects like this:

$ find -name \*rej

If you get no output, go ahead and compile the kernel, install it, and
reboot.  Then run:

$ uname -r

If it shows the string you appended to EXTRAVERSION, you are indeed
running the patched kernel.
