    hp 1020 not detected whitout sudo

    Hello.
    I'm using Ubuntu 9.10 beta, kernel 2.6.31-11-generic.
    My usb-printer is hp laserjet 1020. But it is not detected by lsusb:
    Code:
    $ lsusb
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    dmesg log after plug-in printer:
    Code:
    [23558.836847] usb 1-4: new high speed USB device using ehci_hcd and address 5
    [23558.989752] usb 1-4: configuration #1 chosen from 1 choice
    [23558.993521] usblp0: USB Bidirectional printer dev 5 if 0 alt 0 proto 2 vid 0x03F0 pid 0x2B17
    [23560.549277] usb 1-4: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
    However lsusb with superuser's privileges:
    Code:
    $ sudo lsusb
    Bus 001 Device 005: ID 03f0:2b17 Hewlett-Packard LaserJet 1020
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    How can I fix it?
    p.s. other usb devices work good (such as scaner, flash).
