last bit of output
uhci 0xc400 setting run to 1
uhci 0xc400 cmd 0x1 sts 0x0
uhci init: cmd 0x1 sts 0x0 sof 0x50 flb 0x5a000 frno 0x0 psc0 psc1 0x80

i added some debugging to determine that one actually finishes
the routine and returns to usbinit in devusb.c.  on my screen
i see hub 0, 1, 2, 3, 6 on my screen.  there's some stuff that's
scrolled off.

it appears to be hanging on a context switch or in an interrupt.
perhaps even an smi interrupt.
