HP LaserJet P1005 USB Printer under FreeBSD 8.0-RC2

[Ondřej Majerech]

Hello list,

I had my HP P1005 printer working just fine under 7.2-RELEASE, but I
just updated to 8.0-RC2 and the driver doesn't seem to like the new
USB stack.

I was using the foo2xqx driver [ http://foo2xqx.rkkda.com/ ] -- with
this driver, the firmware needs to be sent to the printer each time it
is turned on, like this: cat sihpP1005.dl > /dev/ugen0.0.

Now, according to dmesg, the printer is now known as device
/dev/ugen2.2, but I can't send the firmware to it (and I can't send
the firmware to any other ugen* device either):

cat sihpP1005.dl > /dev/ugen2.2
cat: stdout: Input/output error

(Trying the same as root or with sudo doesn't make any difference.)

My /etc/devfs.rules:

add path 'da*' mode 0660 group operator
add path 'usb' mode 0777
add path 'usb/*' mode 0666
add path 'usbctl' mode 0666
add path 'ugen*' mode 0777

ls -lh /dev/ugen* with the printer connected and turned on:

lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen0.1 -> usb/0.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen1.1 -> usb/1.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen2.1 -> usb/2.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 20:31 /dev/ugen2.2 -> usb/2.2.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen3.1 -> usb/3.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen4.1 -> usb/4.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen5.1 -> usb/5.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen6.1 -> usb/6.1.0

Googling around for possible solutions didn't turn up anything
successful for me.  I asked on the FreeBSD Forums and was told to turn
on debug informations on ugen by sysctl hw.usb.ugen.debug=1 -- I did,
but I don't see anything new in dmesg or /var/log/messages -- maybe I
don't know where to look?

Anyway, any suggestions?
