I just received my plug and spent today getting it setup.
I plan doing some general IO using the flexel chip and the usb board.
Very cheap on ebay.
http://www.web4robot.com/USBLab.htmlIt has a few preconfigured modes including one with 2 14bit A2D inputs 8 general IO ports and a couple of analogue outs.
My biggest problem with this is that the plug has only one USB port.
I want to use a USB 3G broadband modem for network access and I don't want to have to use a usb hub.
I'm sure I read somewhere in the docs that there are two USB ports - is one of them simply missing a socket?
I wonder if the plug can provide sufficient power for the USB modem too.
