alright, i've set up my arduino with the shield, installed the libraries in the arduino IDE, and loaded the "Button" example code. the IDE verified and uploaded it to the arduino with no errors.
when i connect the arduino with the shield to the MOD via the "MAIN" jack on the shield, the MOD gui also says "no control chain devices connected".
so i guess that points to some issue in the MOD, since both peripherals fail?
thanks for investigating, @falkTX -- let me know if there's something i can test!
btw... i'm on ubuntu, and i checked the MOD gui in both Firefox and Chrome, just in case it's some weird browser thing -- same result in both browsers.
also, both LEDs (amber and green) on the MOD control chain jack are ALWAYS lit -- it doesn't matter whether anything is connected or not, and there's no change (not even a flicker) when i connect a control chain peripheral. is that normal? (there is some activity in the LEDs during the MOD bootup, but once it's up and running they stay on no matter what.)
