    Hi,

    I just bought an Epson 2480 scanner. I'm currently at trying
    to make things work for ordinary users, sane-find-scanner works
    for normal users, but scanimage doesn't.

    Following the instruction I run as root:
    # sane-find-scanner -q
    found USB scanner (vendor=0x04b8 [EPSON], product=0x0121 [EPSON
    Scanner]) at libusb:/dev/usb0:/dev/ugen0
    # scanimage -L
    device `snapscan:libusb:/dev/usb0:/dev/ugen0' is a EPSON EPSON
    Scanner flatbed scanner

    And I have even succesfully scanned the warranty in pnm.

    Then as ordinary user:
    $ sane-find-scanner -q
    found USB scanner (vendor=0x04b8 [EPSON], product=0x0121 [EPSON
    Scanner]) at libusb:/dev/usb0:/dev/ugen0
    $ scanimage -L

    No scanners were identified. If you were expecting something
    different, check that the scanner is plugged in, turned on and
    detected by the sane-find-scanner tool (if appropriate). Please
    read the documentation which came with this software (README, FAQ,
    manpages).

    I have tried to indicate the device for scanimage but with no
    result:

    $ scanimage -d libusb:/dev/usb0:/dev/ugen0
    scanimage: open of device libusb:/dev/usb0:/dev/ugen0 failed:
    Invalid argument

    Then I have tried to remove one of the devices and to change
    libusb with snapscan which is supposedly the backend driver.

    Any clues?

    Thanks, Erik
