new USB driver

[Hans Petter Selasky]

Hi,

I have ended up with a new USB driver :-)

changes:

 - uses mutexes instead of splusb()
 - new EHCI, OHCI and UHCI drivers (only EHCI and UHCI tested)
 - new USB driver interface
   - uses one block of memory instead of many smaller ones
   - no allocation of memory during transfers
   - mutex capable
   - new method to clear stall without having to sleep

 - 100% locking safe
 - some bug fixes

I wondered if I could have my new USB driver up for discussion?

What do you think about it?

Could I have gotten a new directory /sys/dev/usb2 to develop it?
