Check this

General USB Troubleshooting in Windows 2000

I would think you should first do windows update going to http://windowsupdate.microsoft.com 
and then restart the machine if all are present

Updated USB 2.0 Drivers Are Available in Windows 2000 Service Pack 4 (SP4)

Post back if the updates help

Still if doesnot work , try to check if 'Plug and Play' service is running
go to start ---> run ---> services.msc
scroll down to plug and play and start it and make the startup as automatic.

See if that would help .. Check  by connecting an USB device and see if windows would recognise it

Oops. I forget about that.

I reecently installed a new hard disk and during the process reset the bios to mininal default to trouble shoot a boot-up problem. This setting disables the USB, and I forgot to manually enable it later.
