Ok, thanx, I let the iduino folks know that you did not have a problem with 11 and xp and asked them to get back to me if they look into it.
The main thing that jumps out at me is that I loaded arduino 0010 first and plugged in a usb freeduino and loaded the drivers, and you did not. I passed that along as well.
Ok, but it sounds like a new iduino on new arduino 0011 install stands a reasonable chance of working (on xp anyway). It looks a lot simpler to prototype with and usb on board and $18, I'll stick my neck out and keep suggesting the iduino I think
