Thank you Patrick,
'loaded all the libraries - just bringing up the Phidget Control Panel and launching the "Interface Kit-full" I immediately get the following message: "Tuesday, December 13, 2011 5:43:58 PM: Channel 7: 8 sample overrun detected.", which is consisent with issues I've seen with my own software. I'm connected directly (via cable) to my SBC2, so the indirect issues with the wireless aren't coming into play.
I can run the software, and interact with the SBC, but it just seems there shouldn't be an overrun message when you start up. I'll send more as I play around with things...
