As soon as I removed this, the irq storm and unhandled disconnect stopped. Plus, the bit shifts match exactly what we see on original musb registers, so we might as well leave musb core handle it by just passing around int_usb to it. Remember that the only thing that's am335x-specific is the ability to reset the IP :-) MUSB core already had knowledge of babble. -- balbi
