Felipe, 

Another issue with the whole series:

testusb with g_zero fails on some OUT transfers:
I ran this:
sudo ./testusb -a -t 1 -c 1 -s 4096

On the OMAP, I see only 512 bytes were received,
and DMA is still waiting for the remaining 3584
bytes. Maybe a bug in the Autoclear handling?

IN transfers went through okay.

Will debug some more tomorrow. Any chance you can give this a
shot on your boards as well?
