Please do the following test:

- Plug in and turn on your HP device on USB.
- Do "lshal > hal.txt" and search for the model name of your HP device in hal.txt. Look for the "linux.device_file" entry in the section where you have found the model name.
- Do not unplug or turn off your HP device.
- Now do "sudo chgrp <your user name> <path from "linux.device_file" entry>
- Now try to scan or try to read out the ink/toner levels. Does it work?

I have tried this after removing my user name from the "scanner" group in /etc/group and then logging out and logging in again. It works. SWo HAL must set the group ownership of the /dev/bus/usb/XXX/YYY file of the device to the user's group. Permissions must be 660.
