Wow that's hilarious, nice work. What is the missle hardware? Was it difficult to get the driver?
I have a project where I'm trying to interface the Chumby with a Phidget relay board. I posted in the hardware section but got no reply. I'm told the Chumby One has built in drivers for the Phidget, but alas I have a Chumby Classic.
As far as getting the widget to appear in control panel, I have a feeling a widget downloaded from the web won't be able to access your USB port since the widgets have a pretty restricted security model. If it comes from the web, it can only access the web. Silly if you ask me, but such is life. But I think there is a way to get a widget from a thumbdrive to appear on your control panel, though I don't know what it is.
