Following this email I am sending patches to revert upstream commit:

    xhci: don't finish a TD if we get a short transfer event mid TD

This commit is causing a regression upstream (see [1] e [2]) and has been
included is several stable kernels.  The only ubuntu kernel currently not
affected is wily, all others seem to be affected (although I haven't done
a thorough search in launchpad for more bug reports).

[2] https://bugs.debian.org/808953

There's currently no upstream fix yet, and since we're starting a new
cycle next week, it's probably better to just revert this commit for now.
