I am having periodic problems with the odd u3g device that gets hung.
If I try and reset it, it totally locks up and I need to do a reboot of
the box the recover. Apart from usbconfig reset are is there anything
else I can do to recover from such a situation ?

I have also tried post reset
# usbconfig -d 1.3 set_config 255
# usbconfig -d 1.3 set_config 0
usbconfig: could not set config index: Input/output error

This is RELENG_8 on an alix box from July 14th.
