hi,
I encountered some problems connecting a usb-scanner (usb2). Since I found
only postings in newgroups that report similar problems but no solution, I
hope someone here can help.
OS: Debian Sarge
Tested Kernels: 2.6.9, 2.6.10-rc1, 2.6.10-rc3

lsusb reports:

Bus 001 Device 001: ID 0000:0000
although the scanner is connected.
Other usb-devices such as memory sticks work normaly. I tried to disable ehci
but this didn't improve the situation. And the scanner already worked
successfully with a 2.4 kernel a year ago.
Hope someone can clear up.
TIA.
Alex
