OHCI controllers and bulk transport

Has anyone had any problems with, specifically, bulk transport on an OHCI
controller? I have a development system and a test system, and the only real
difference between the two is that the development system has a uhci
controller and the test system has ohci. I am able to send urbs down the
uhci controller fine, but once I move onto the test system, the urbs are
stuck in a busy state. Any insights? Sorry that this is a bit vague, but
this is all the info I have at the moment.
