I have a Sony Vaio FX150 laptop.

I just got a Microsoft Optical USB mouse (with wheel), but it won't work in Linux. It works very well in Windows 2000. When my machine boots up, the light under the mouse turns on until it gets to the point where it says "Initializing USB Subsystem [OK]" or something like that. Then, when it gets to the point where it is bringing up eth0 (which says [OK] also), the mouse lights back up. However, when it reaches the login prompt, it prints "usb_control/bulk_msg: timeout" about 100 times or so and stops. The light on the mouse stays on, though.

Now, when I cat /dev/input/mouse0, it tries to output things, but when I move the mouse, nothing prints. When I cat /dev/psmouse it outputs my touchpad.

Does anyone know a way for me to fix this?

Have you by chance tried "modprobe hid" and then "modprobe mousedev"? I don't know if you setup has HID and mouse support compiled as modules or not, but that might be worth a shot.

modprobe hid and modprobe mousedev didn't work. Any other suggestions?
