When I try and print something to my Brother HL-1250 printer via USB,
the printer resets itself causing the following messages to appear.

	ulpt0: at uhub0 port 2 (addr 2) disconnected
	ulpt0 detached

Once the printer reset is complete a second or so later, the printer
device is reattached.

	ulpt0 at uhub0 port 2 configuration 1 interface 0
	ulpt0: Brother Industries product 0x0007, rev 1.00/1.00, addr 2, iclass 7/1
	ulpt0: using bi-directional mode


bash-2.05$ cat foo.pcl > /dev/ulpt0 
bash: /dev/ulpt0: Device not configured

Just opening the device is enough to cause this.
