I'm now digging in to running USB on a PIC32. In the past, I've just used
chips from FTDI or Silicon Labs to convert USB to a UART. I'm playing with
the PIC32 USB Starter Board and trying to figure out what direction to go
here.

All I really want to do is pass bytes from the host to the USB device and
have it send bytes back, just like a UART. Microchip provides a demo using
the Communications Device Class. I have their demo working and am playing
with adapting it to my needs.

I understand that most OSs include standard drivers for various USB
devices. Is this the case for CDC devices? Can an application talk to a
CDC device without having to install any drivers?

Is CDC the most appropriate class to use in such an application? I'm just
sending ascii commands and getting responses.

Thanks!

Harold
