uhub0: device problem (SET_ADDR_FAILED), disabling port 2 printer

I keep getting this message when I plug my printer into the USB port:

uhub0: device problem (SET_ADDR_FAILED), disabling port 2 printer

This is the output of `usbdevs -v`:

ontroller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \
VIA(0x0000), rev 1.00
 port 1 powered
 port 2 powered
Controller /dev/usb1:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), \
VIA(0x0000), rev 1.00
 port 1 powered
 port 2 addr 2: full speed, self powered, config 1, Generic USB Hub(0x9254), \
ALCOR(0x058f), rev 1.00
  port 1 powered
  port 2 powered
  port 3 powered
  port 4 powered

The usb port seems to be working just fine, because I can connect my sister's
usb digicam to the port (dev/da0).

The printer is a Samsung ML-1510. I used this printer with 4.[7-10] and 5.4 and
never had any problems with it.

Here's some info from /var/run/dmesg.boot:

usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
usb1: <VIA 83C572 USB controller> on uhci1
usb1: USB revision 1.0

uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1

uhub2: ALCOR Generic USB Hub, class 9/0, rev 1.10/1.00, addr 2

I'm using 6.0-BETA4 FreeBSD 6.0-BETA4 #0: Wed Sep 14 00:54:49 CEST 2005

Cheers.
