HP PSC 2175 printer USB doesn't work

[Goncalves Dominique]

Hi

I have a HP PSC 2175 printer USB, I have installed from ports cups, hpoj
and libusb. ( FreeBSD 5.3-RC2 )

My printer is detected : 

venus# dmesg | grep ulpt
ulpt0: Hewlett-Packard PSC 2170 Series, rev 2.00/1.00, addr 3, iclass
255/204
ulpt0: using bi-directional mode

To configure cups I must before configure hpoj driver but 
ptal-init script fails to find my printer

venus# /usr/local/etc/rc.d/020.ptal-init.sh.sample setup

Stopping the HP OfficeJet Linux driver.
.....
Probe for USB-connected devices ([y]/n)? y

Probing "%/dev/usb0%/dev/ugen0"...
No device found.

.....
Starting the HP OfficeJet Linux driver.
No hpoj devices have been configured.
As root, run "/usr/local/etc/rc.d/020.ptal-init.sh setup".

In /var/log/messages, i can see : 

Nov  3 10:37:33 venus ptal-mlcd: SYSLOG at ExMgr.cpp:652,
dev=<mlc:usb:probe>, pid=19133, e=2, t=1099474653         ptal-mlcd

device!

I suspect a problem with the version of the ports of libusb.
On the mailing list of the driver hpoj, it is indicated on several
occasions that it is necessary used the last version of libusb so that
hpoj functions under FreeBSD.

The ports version of libusb is 0.1.7_1, and the official webiste of
libusb :

"The current stable version of libusb is 0.1.8. This release fixes a
variety of bugs on all platforms and compile problems on BSD platforms.
It is highly reccomended to use this version."

Why libusb is not upgraded?. An upgrade could break other ports ?

Thanks for your help

PS : sorry for my bad english
