This resulted in a different approach that solves it at the USB core level:

http://www.spinics.net/lists/linux-input/msg42369.html

If this were to go upstream, that would likely solve both this bug and bug 1270160, correct?

Nevermind.  It looks like upstream dropped that immediate patch for now.
Comment 7 Josh Boyer 2015-12-01 20:07:05 UTC 
Fixed in git on all active Fedora branches.  Thanks for the patch and the work upstream!
