4d8c7e2781 Make the USB subsystem unloadable and detachable, though currently 
a significant amount of memory may be leaked each time a host
controller is detached.

5b775a536b Attempt to follow the correct procedure for synchronising with the 
system BIOS to disable legacy device emulation as per the "EHCI
Extended Capability: Pre-OS to OS Handoff Synchronisation" section
of the EHCI spec. BIOSes that implement legacy emulation using SMIs
are supposed to disable the emulation when this procedure is performed.

dd6baeae21 Implement basic support for EHCI interrupt pipes. This is unlikely 
to be particularly correct or optimal, but it seems to be enough
to allow the attachment of USB2 hubs and USB2 devices connected via
USB2 hubs. None of the split transaction support is implemented in
our USB stack, so USB1 peripherals will definitely not work when
connected via USB2 hubs.
