Hi Sarah,

No, this patch isn't used for UAS driver. It's used by us only for several
tests that we implemented in the user space unittests framework we released
with this patch. We used this FW to test our superspeed support
implementation and the UAS gadget driver. It's a userspace application that
uses Google test and libusb.
That's the only reason we need this patch at the moment.
But in any case, due to the comments we got on it from Greg/Alan/Felipe this
patch is rewritten at the moment by its original author Amit Blay
(ablay@...eaurora.org). He'll post a new version of it once he's done.

Thanks,
Tanya Brokhman
