USB mouse problems

[Piers Kittel <debian@biased.org>]

Hi all,

Have got an standard USB Intellimouse - I put in a new hard drive, 
installed Debian, and basically it worked just fine.  Then I had to 
remove the hard drive and go back to my old install, but the mouse 
doens't work there, and I've mounted the drive I had to remove and 
checked all settings on both drives and they both seems to be the same 
but still won't work on the old install - can anyone help?

I've got the following modules loaded (relevant to the mouse):

mousedev                4148   1
input                   3520   0  [mousedev]
hid                     9976   0  (unused)
usb-uhci               23344   0  (unused)
usbcore                61932   1  [hid usb-uhci]

and the USB subsystem driver outputs (on bootup):

Sep  6 09:26:21 deaf-pc15 kernel: : USB HID v1.00 Mouse [045e:0009] on 
usb1:2.0

In my XF86Config-4 file I've got the following:

Section "InputDevice"
        Identifier      "Generic Mouse"
        Driver          "mouse"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ImPS/2"
        Option          "Buttons"               "5"
        Option          "ZAxisMapping"          "4 5"
EndSection

and

        InputDevice     "Generic Mouse"         "SendCoreEvents"

in the "ServerLayout" section.

Any ideas of what I'm doing wrong?

Thanks very much for your help in advance!

Cheers - Piers
