I misread this comment near the start of the file: * Note that all HCD drivers do URB_ZERO_PACKET and timeout properly, * so we don't have to worry about that anymore. Since the OHCI and EHCI drivers don't support timeout properly, I still find the comment a little puzzling. > > That's a project for the future.

You misunderstood -- I meant that when I remove timeout support from the UHCI driver I will put it into the USB core instead.
