Hi,
Delete the Mouse from the Device manager and reboot, to let windows
reinstall it.Get the latest Drivers for you mouse.
If this doesn't help then you have to do the following:-
If you have a serial mouse on COM1 or COM2 that occasional fails to be
detected at startup, you can just fiddle with connector, without the
need to reboot, by adding value entry OverrideHardwareBitstring as a
type REG_DWORD to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Sermouse\Parameters
A data value of 1 indicates that the mouse is installed on COM1 and a
data value of 2 specifies COM2.
This entry causes the driver to load, even if the mouse is not detected.
