Whew! Some workaround.

Bruce, I was thinking that you were probably the most qualified too. 
I do most of my programming in the embedded world and some on 
Windows. But I haven't even begun touching device drivers for 
Windows. I don't have the DDK and I also don't have MSVC++ (but that 
may change sometime in the future).

If you are willing to share your device driver that would be great! I 
would think that all that would be required is to license it under an 
OSI <http://www.opensource.org/> approved license.

I do have a couple of questions:
1. Is this driver for XP only? Or will it work for NT/2K/XP?
2. Would the loaddrv.exe program that comes with the Windows avrdude 
be able to load your driver? Or, how would you go about loading it?

Thanks for all your help.
