usb to uart bridge? it is going to be SMT unless you buy one 
pre-soldered on an adapter board. check www.silabs.com or 
www.ftdichip.com .

I'm really just here to listen, but I'm doing a bit of USB stuff right 
now for a sort of similar project (dsp module, with a microcontroller 
for CV inputs, USB bootload programmer, display, and possible USB MIDI). 
Just got my USB HID firmware going for a Silicon labs 8051, and have 
done some with the PIC USB controllers. I would say add a USB 
microcontroller (atmel/PIC/Silabs) that converts USB to whatever, but it 
looks like your hardware is already complicated enough.
