Communicating with USB port with C# and figure out protocol

Does anyone know of any c# code example of listening to and logging the communication to and from a USB device?

My problem is as follows: I have a Weather Station (265 NE) which I connect to the computer via USB. The provided 开发者_开发技巧application for transfering data from the weather station i quite crappy. Now I'd like to write an application that handles the communication for me. Therefor I need some code example showing how to figure out how the weather station and the computer communicates and then reproduce the communication from my own piece of code.

I've googled a lot to find an answer to this but with no luck.

Cheers

Martin
