I've just pushed out to sources a new USB implementation, courtesy of nemo, who debugged and repaired our old UHCI and OHCI drivers, wrote a new EHCI driver for USB 2, converted the user-mode drivers in /bin/usb and tested it all, among other things. Thank you, nemo.
I've updated on sources at least /386/9*load* (though they contain no USB code), /386/9pc*, kernel sources, manual pages and a few scripts in /rc/bin. Tomorrow's CD image should incorporate all this. devusb has a new interface, so it is named #u, to distinguish it from the old one, #U. If usbd is compiled into /boot, /boot/boot will run usbd at start up, thus permitting the use of USB keyboards, mice, disks, etc. at boot time.
