http://ubuntuforums.org – 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).
