Microsoft has an article on their site: How to disable the use of USB storage devices [support.microsoft.com] that should get you headed in the right direction. A quick perusal of the search engines show a number of other methods to accomplish this.

Method one Remove the driver files for those USB ports and replace them with another file of the same name but empty. Restart and cross your fingers.
Method two Mix three parts epoxy resin with one part hardener, place into the corner of a plastic bag, roll up the other end as if you wanted to do icing, and then snip the tiny corner which should now be full of pressurised hardening resin. Squeeze the bag and position the tip so that resin pushes its way into the USB ports, securely ensuring that they cannot be used for any devices.
Method three If you are lucky, your ports are not directly soldered to the board but are actually connected by wires. Remove case. Remove the wires from the board or the back of the port. Replace case.

Rather than using hacks, open the device manager and disable all USB ports, etc.
If this isn't good enough, you can view the device driver files from here and delete them by sneaky means (but if you don't know what you're doing, you'll kill the whole system). I'm not going to explain further.
