Great suggestions so far. I was hoping for a complete board. For the
moment I just want a working PC I/O device. With an easy way to attach
all of the wires. I am going to worry about the the rest of it and make
my own board last. I screw the board(s) into the side of the project
plug in the PC to the USB and start wiring it up.
For the 48V Solenoid I was intending to use a 48V power supply with a
Power Transistor (MOSFET) driven by the USB I/O device (one wire over)?
PC Fires the Solenoid. It would be nice if it could fire it for n
seconds rather than turn it on.
For the light I was thinking similar to the Solenoid but the light would
be powered by 9V or 12V. PC able to flick the lights on and off.
For the contact switches I was hoping just to have two wires back to the
USB I/O that when contacted would send a message back to the PC by USB.
So I was really looking for good completely build USB modules and why
you would pick module made by company A over company B. Since I want
between 2 and 5 USB devices cost is an issue.
thanks

The mbed uC might be just the perfect solution. It has an RPC (Remote Procedure Call) feature that allows you to declare objects and then control them
