The issue was that we were using getStatus every time we polled for new
devices which suposedly (I fixed few other bugs in the code I used at
the time so, I'm not sure) drove hub in my USB keyboard crazy. The
correct way is to poll interrupt pipe.
Another thing I added is the ability to do background transfers. It is
important for USB keyboard support because otherwise we lose messages on
keyboard interrupt pipe. It triggered a bug in uhci module. Now there
are 2 issues:
1) code is new or modified. Needs testing.
2) On yeeloong the data read from mass storage is sometimes corrupted.
Happens in mainline, not sure about other branches. It seems that it
wasn't the case before. It's either a regression (perhaps from my code
for partial transfers) or cache issues (some cache isn't correctly flushed)

Yes, a test run of keylayouts branch on your hardware would be helpful.
Especially I'm interested if USB data corruption happens in your case too.
