So on 3.1 low resolutions work for usbip but high resolutions don't.
As near as we can tell they never have, so it's not a regression.

File a bug on http://bugzilla.kernel.org explaining:
1) Which resolutions you tested (working and not working).
2) What you mean when you say it doesn't work.  What were the error
   messages etc?

When it comes time to move this out of the staging directory, we'll
look through bugzilla and see what bugs it has.
