beginning driver development

[davoid at softhome.net]

Hello, 

I am a junior programmer, and I have to write a driver for a USB wireless 
network card( I've heard it's an Atmel-based card -- Network Everywhere 
NWU11b ). I know of 3 different drivers for this card that are said to work 
on Linux, I will therefore inspire myself from them, of course. However this 
_is_ my first contact with a kernel from a developer's point of view, and I 
don't know how to start. Can you help me? 

Thanks!
Andrei
