Okay so it hands you back an unsigned int, no cap.

This is the mode selection filter. Its whole job? Block UDMA on devices that cause trouble with this controller. That's it. If a device is giving this controller grief, UDMA gets blocked. Not me guessing — that's literally the documented behavior. 💅
