</div>It's always best to start with one end. Start with either something on<br>
the PIC or on Linux.<br>
<br>
Chances are high that you'll find that every driver you need is already<br>
available in Linux. The Microchip firmware examples should just work<br>
with Linux class drivers (hid, cdc-acm, usb-storage), and you can also<br>
do a lot of stuff in userspace if all you need is to "communicate with"<br>
the PIC18F4550. See e.g. <a href="http://code.google.com/p/picusb/" target="_blank">http://code.google.com/p/picusb/</a><br>
<br>
So, play with the Microchip examples, find out what you want the<br>
firmware to do, and develop it. If it needs a new Linux device driver<br>
then I'll be impressed :-)<br>
<br>
And more GPL'd firmware examples are always nice to have. There are<br>
already quite a few to start from. PUF has been there for ages:<br>
<a href="http://vasco.gforge.enseeiht.fr/" target="_blank">http://vasco.gforge.enseeiht.fr/</a> . I'm sure Google will find others.<br>
But I'm getting a bit off topic here now...<br>
