USB keyboard status indicators not working

[Sam Banks]

It appears, in my case at least, that the TD to change the
LED state on the physical keyboard is stalling. I have
attached the output of this with hw.usb.uhci.debug up high.

Does anyone have any tips or documentation on debugging
stalls?

Cheers,

Sam.
