Hi, All !
I have problem with my USB. When I attach any device, Linux doesn't detect
that. It's not a problem with hands ;), because I attached same USB devices
to my home computer without any problems. And it's not a problem with
hardware - windows detects any devices without any problems.
I use kernel version 2.4.21, 2.4.22.
Can anybody help me ?
