I don't know exactly what happened, but after upgrading udev to unstable version and a reboot, lsusb works correctly. When I rebooted the machine, I used sane-find-scanner to detect scanners. It worked. Then I used "xscanimage" but this did not worked because it got a problem connecting to the scanner. >From that moment, I cannot use any USB device via libusb: when trying again to identify the device I get a lot of "Operation not permitted" and "Connection timed out": [EMAIL PROTECTED]:~$ lsusb Bus 002 Device 001: ID 1d6b:0001 Bus 003 Device 001: ID 1d6b:0002 Bus 001 Device 006: ID 04b8:011f Seiko Epson Corp.
