I'm glad you asked that, because it prompts me to ask something I wasn't sure about.

Looking at the photos in that Wiki, it looks like there's a 6 pin ribbon cable & connector like that on the AVR programmer - so I'm assuming there's "something else" not mentioned to connect between USB (can't see anything USB on the Walrus board) and the board.

So do we need some sort of USB-<something> adapter as well as the Walrus board ?
