I think you are supposed to use udev and /etc/udev/rules.d/
Geting up HP Printer on CentOS 5.x when USB 2.0 does not work properly:
modprobe -r uhci_hcd; modprobe -r ehci_hcd; modprobe uhci_hcd; modprobe
ehci_hcd
usb_printerid /dev/usb/lp0
udevd restart
service haldaemon restart
If firmware loading during intallation does not work, use:
make install-hotplug !!!
(in /etc/udev/rules.d add 11-hplj10xx.rules file ???)
