USB mouse problem since upgrading to kernel 2.6.15

[André Wendt <andre.wendt@web.de>]

Hi,

I'm using a custom kernel 2.6.15 and X.org 6.8 on a "testing" laptop. All
of a sudden, I cannot get my USB mouse to work. I have not changed
anything in the kernel config concerning USB devices.

Symptom: When I plug in the mouse, kernel 2.6.12 reports in /var/log/syslog

Mar  5 21:50:01 localhost kernel: usb 2-2: new low speed USB device using
uhci_hcd and address 6
Mar  5 21:50:01 localhost kernel: input: USB HID v1.00 Mouse [Microsoft
Microsoft 3-Button Mouse with IntelliEye?] on usb-0000:00:1d.1-2

and everything works fine, whereas kernel 2.6.15 reports an additional line:

Mar  5 21:28:28 localhost kernel: usb 2-2: new low speed USB device using
uhci_hcd and address 4
Mar  5 21:28:29 localhost kernel: input: Microsoft Microsoft 3-Button
Mouse with IntelliEye? as /class/input/input6
Mar  5 21:28:29 localhost kernel: input: USB HID v1.00 Mouse [Microsoft
Microsoft 3-Button Mouse with IntelliEye?] on usb-0000:00:1d.1-2

and the mouse does not respond.

How can I determine what the problem is? Any hints would be greatly
appreciated...

Thanks,
André
