Its a cfstix, I noticed this difference from a photo I saw on a webpage, maybe mine must be of a new design???
It has a power connector and LED like those on the tweener (perhaps this is the reason it doesn't work!).
Has anyone else seen this?

Tried that, nothing comes on.

Sorry slight mis-spelling in my post, i'm not using a robostix here I meant to say "when I connect up the gumstix with the tweener".
I am actually intending to use a robostix in combination with the cfstix and gumstix in the long run, but
the robostix wasn't in use for this experiment. This was just using the cfstix, gumstix and tweener.

If the power LED doesn't come on when you lug in the cfstix by itself,
then I would think that the cfstix is dead.
I'd contact the gumstix folk and confirm.
