Hi

Had similar trouble with an Epson. It was explained to me by the team that usb printing can go through ulpt or ugen. Though in principle both could be available, no one has been able to assume the responsibility to make this always happen. It needs someone with the skill and the will to do so. The team is small and flat out at all times.

Disable ulpt in the user kernel configurator:

# config -ef /bsd
ukc> disable ulpt
ukc> quit

The kernel will now rebuild without ulpt.

# echo "chown _cups:_saned /dev/ugen0.* /dev/usb0" >>/etc/rc.local
        (as suggested in /usr/local/share/doc/pkg-readmes/cups-1.x.xp0)
# reboot

Now set up through cups as normal

Good Luck

Hello,

i'm trying to configure my printer with CUPS. I connected the printer via
USB.
I installed cups and gutenprint, because the printer is supported by
gutenprint.

dmesg output:

ulpt0 at uhub3 port 1 configuration 1 interface 1 "Canon MP620 series"
rev 2.00/1.10 addr 6
ulpt0: using bi-directional mode

I changed the rights of ulpt0: `chmod 0666 /dev/ulpt0`

CUPS backend is recognizing the printer
`/usr/local/libexec/cups/backend/usb`:

In the webinterface the printer does not show up. The printer works with
Debian Linux
with CUPS and gutenprint.

The Scanner (its a multifunction device) works without configuration with
xsane.
