You can probably do that with most microcontrollers. Several DPRG
members are using Atmel AVRs or New Micros IsoPods (or ServoPods) for
this job. A couple of us are using the MiniRoboMind (68332) boards. You
can talk to any of these boards from Linux over a serial port pretty

If the source is under a free license, perhaps it can be ported to run
on a non-proprietary OS like Linux. The Linux USB system is well
documented and there's plenty of source code available to start from.

If you need something totally off the self, the latest Linux kernels
include USB drivers for the Phidget USB servo controller boards. I don't
think they're cheap though.
