That might be a little more than you want to tackle at this point.

Robo-Ware Robotics Control Software
http://www.rentron.com/Robo-Ware.htm

With the Mini SSC II and Robo-Ware you can drive 8 servos, and the software allows you to do all kinds of different programmed motions with a PC program, or a PIC (with PicBasic Pro).

It's not USB, but it's still cool.
