USB-Device Read Stream

Question

Hello,
i have a GPS-USb-Stick and i would like to read the GPS-Coordinates from it with a C# program. But i don´t know how to start :(
Can anyone help me to the right path? Which DLL´s do i need, how does it working with the Drivers from the stick etc.
I haven´t doen this before and i can´t finde any helpfull thread in the www.
