I don't use either of those ..

this is just a plain old hotplug script with
/etc/hotplug/usb/hplj.usermap:
hplj1005 0x0003 0x03f0 0x1317 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00
0x00 0x00000000
/etc/hotplug/usb/hplj1005
waiting and catting the firmware into the device node.

currently the script is scanning all devices for a supported one .. is
there some variable in a hotplug script to read out the device node?

udev-068
