Problem with installing HID devices

[DanCake0]

I've got a nice new USB mouse and keyboard bundle which relies on the "Human Interface Device Access" service to run.

I've plugged them into my laptop and they detected and installed fine unfortunately i've always had HID problems on my main pc since upgrading to SP2. I couldn't even start the service due to missing files but this was soon fixed by doing the following:

Provides a generic interface to Human Interface Devices (HID) like keyboard, mouse and joystick for accessing, configuring and maintaining hotkeys.

This service can become important if fx. having a keyboard with extra buttons/hotkeys for controlling sound volume, or if using USB Speakers.

Note if getting the error below when starting the service, then one have to open the archive <install-cd>\i368\Drivers.cab and extract the following files to %SystemRoot%\System32:
hidserv.dll
mouhid.sys
mouclass.sys
Event ID: 7023

Could not start the Human Interface Device Access service on Local Computer.
Error 126: the specified module could not be found.

As soon as I plug it in, wants drivers which it shouldn't even ask for since it's built in and the status in device manager is:

The drivers for this device are not installed. (Code 28)

To reinstall the drivers for this device, click Reinstall Driver.

Does anyone have any ideas on what could be wrong? I've also had this problem with a previous install when it can to installing a bluetooth dongle.

Thanks
