    printer not detected as user

    My HP1020 printer is not detected when i run lsusb as a user, therefore i can't add this printer in cups. But root can detect it. I have another printer, HP C4200, which is detected as a user. What's the problem?

    :~$ lsusb

    Probably a permissions issue with the port or udev.

    You might prove a rare case, but I'll hold out why until later, lest I prematurely incur the wrath of my colleagues .

    I'd first suggest you try setting up the printer directly in CUPS with the web interface:

    You just WON the game!

    Permissions

    when i run ls -l /dev/bus/usb/001/ the device corresponding to HP 1020 haven't read permission to the "others" group.....but all of the others devices have it.
    How i fix it?

    By cups web interface the usb is not detected too.

    Have you installed HPlip, from your system repos? It's usually a great help to me. They also have a ton of helpful FAQs and HOWTO's.
