hp 1020 not detected whitout sudo

[Ruslan T.]

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:

$ 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:

[23558.836847] usb 1-4: new high speed USB device using ehci_hcd and address 5

However lsusb with superuser's privileges:

$ sudo lsusb

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).
