Hi petrobe41,

Is there anything showing in Device Manager as ‘Unknown Device’? If so update the driver following the ‘Have Disk’ instructions below.

If nothing is showing at all, as a last resort, uninstall all devices listed under ‘Universal Serial Bus controllers’ and then shut down.

Remove the AC power adaptor and battery and then hold down the power button for 30 seconds.

Re-attach the AC adaptor and battery, re-boot and let Windows reinstall the drivers.

If at that stage you have an unknown USB device listed in Device Manager then update the driver using the original Vista Pointing Device driver that can be found in the original drivers folder (Pointing sub-folder).

You will need to use the ‘Have Disk’ method.

Extract the files from the installation package to a known location.

Click Start > Control Panel.

Double click Device Manager.

Right click the device and select Properties

Click the Driver tab.

Click Update Driver.

Click Browse my computer for driver software.

Click Let me pick from a list...

Click Have Disk....

Click Browse and navigate to the folder where you placed the extracted files.

Click OK.

Click Next.

Click Finish.

Reboot your system if requested.
