Circuit Board Design and API for a USB I/O peripheral controller for Visual Basic 6.0

I am in need of a circuit schematic that I can in turn use to layour a circuit board. I also need recommendation for ICs as well. I need a design for a 64 input 64 output (128 total I/O) USB board that can easily be attached to a Visual Basic 6.0 application. The board should be able to be individually addressed if there are multiple boards present on one computer. The outputs need to handle 0-60V at around 12A of current. The inputs should accept around 0-30 volts. I don't mind what combinations of boards/chips are used, but I am trying to keep costs as low as possible. Some suggested chips would be from Cypress Semiconductor and Microchip, but anything can be used. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
