problem with mouse pointer on my laptop

[haus_kat]

I have an old Dell running Windows 2000. The USB port isn't working so i have to use the built-in mouse point usually. However when I went to use the computer a few days ago I discovered a weird problem. The mouse pointer will only allow left-clicking so it is very hard for me to do anything on that computer at all. The computer has a touch pad with buttons and also a little rubber thing in between the keys on the keyboard and another set of mouse buttons to go with it. I'm not sure what happened but neither will respond correctly and I ca only get left-clicking. I plugged a borrowed USB mouse into the PS port (with an adapter) and it worked fine, if this gives any clue as to what happened

Try uninstalling USB root hubs and reboot. Go to your device manager and expand USB controllers. There are usually 4 USB hubs and right-click select uninstall, reboot.
