No, it returns 
# usbconfig -u 0 -a 2 reset
usbconfig: could not reset device: Input/output error

Then ulpt detaches
ulpt0: at uhub0, port 1, addr 2 (disconnected)
ulpt_detach:653: sc=0xc317f000

Yes, after the first job:

It looks like there are some problems even with the first job (I missed
this point before).

ulpt0: using bi-directional

If it can help, I can compare with FreeBSD 7.2.

Thank you.
