The C# code will only talk to PIC based usb devices. I dont think there is a general piece of code for C#, or any language.

Hallo
You have to develop individual drivers that match the protocols expected by whatever you have plugged in. Thats why the microchip stuff comes with firmware for the PIC (one end of the USB comms) and a dll library for the PC (the other end of the comms).
As an aside if you're interested in generic USB control have a look at the windows driver development kit. It depends what thing your are plugging into the USB port and what you are trying to do exactly.

and
http://www.microsoft.com/whdc/system/bus/usb/USBFAQ_intro.mspx
Leastways thats my understanding being a relative newcomer to PIC land.

Hi, I mean - The PIC has a USB transciever inside it, it is part of the PIC! So if you have a usb PIC (e.g. PIC18F4550 then you have it!) Mat

This is the software which runs on the PIC.
