here are the usb-related messages that i see.  the device
i've plugged in is an apple kbd.

ehci 0xe0027800: port 5 didn't reset after 500 ms; sts 0x1101
panic: usbohci: epio: io->tok != Tdtokin && a == nil

a slightly older version crashes with an assert a!=nil,

the next older version of usbohci does seem to work, but it complains
about a different problem
