I'm having trouble getting USB to work on a SuSE 9.3 system. I don't know much about how it all works. I tried usbview and it gives me an error "Can not open the file /proc/bus/usb/devices" and indeed /proc/bus/usb is an empty directory. usbview says "Verify that you have USB compiled into your kernel, have the USB core modules loaded, and have the usbdevfs filesystem loaded". I don't know how to check what's compiled into the kernel but it's the standard SuSE kernel (2.6.11.4-21.7-default) so I hope so! And /var/log/messages has this (but only this about usb): Jul 20 22:46:47 piglet kernel: usbcore: registered new driver usbfs Jul 20 22:46:47 piglet kernel: usbcore: registered new driver hub Jul 20 22:46:47 piglet kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic Jul 20 22:46:47 piglet kernel: usbcore: registered new driver usbserial_generic Jul 20 22:46:47 piglet kernel: usbcore: registered new driver usbserial Jul 20 22:46:47 piglet kernel: drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0 There are lots of messages like this: Jul 25 20:43:00 piglet hal.hotplug[26331]: DEVPATH is not set but that seems to be something to do with the CD drive, not USB. lsmod shows: usbserial 34800 0 usbcore 132976 1 usbserial so I guess the core modules are loaded? Should I see ehci or uhci? I don't. ps shows udevd is running lspci -v shows the following controllers: 0000:00:10.3 USB Controller: VIA Technologies, Inc.

I have set hotplug debug to verbose with yast, but I don't see anything in /var/log/messages when I do. I have created a /events directory but don't see anything there. (I rebooted and saw a lot of stuff but nothing when I plug or unplug devices). USB is enabled in the BIOS. The mobo is an MSI K8M Neo-V. I've looked in the admin and user manual, in the suse sdb and mailing list archives, and with google, but haven't managed to find a solution. I'm sure I've missed something obvious, but what is it? Thanks, Dave
