The only thing affecting us is the removal of usb_resetep(). We had a call to 
it in our generic USB layer, but we weren't actually using it. I'd been 
planning to fully remove that part of the code anyway but just hadn't gotten 
around to it yet. Now it's done. Thanks for the motivation. :-)

usb_resetep() (and its equivalents on other platforms) indeed should go away as 
it's a function which, by its very definition, loses data synchronization 
between the host and the device. The clear_halt function does a two-ended reset 
(both host and device) and is the only way a USB endpoint should ever be reset.
