hotplugging mouse hassles

[Adam Hardy <adam.ant@cyberspaceroad.com>]

I have XF86Config-4 configured like this for my mouse:


Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "ExplorerPS/2"
        Option          "ZAxisMapping"          "4 5"
        Option          "Emulate3Buttons"       "true"
        Option          "Buttons"               "5"
EndSection


and for a while now the psmouse driver loses synch and goes nuts when I 
switch the KVM, even though Hotplug should keep it in there, as per this 
/var/log/messages:

Aug  9 15:01:49 gondor kernel: logips2pp: Detected unknown logitech

Does anyone recognise these error messages or know a fix?

Would be v. grateful,
