Just use the built in classes if you can

MSDN[^]

Or you can use Socket.IOControl and the DeviceEndPoint which must be found via another manner.

First, USB is not a "port" it is a bus, not unlike the expansion slots inside your computer. You cannot treat the USB ports like you do serial ports.

Second, how you communicate with the device depends on the interfaces it and its driver exposes. Without knowing that, you're going to get nowhere pretty fast.

One needs to be an idiot to vote 3 for this answer. What's wrong? Could be 4 as a minimum, I voted 5.
