Hello Robert, I checked out the USB Experiment Interface Board K8055:
http://www.maplin.co.uk/Module.aspx?ModuleNo=42857&doy=search Possibly one board would be enough: you could add a simple circuit with mutiplexing chips using the digital input/output pins to select which external analogue input/output is connected to the analogue input/output of the USB card at any given moment. (your main problem is I think to have multiple analogue input/output? You have 8 digital lines to direct I/O to or from the USB I/O pins which gives you quite a lot of scope: 4 lines for in and 4 for out gives you 16 in and 16 out); The driver DLL plus software looks pretty good.
