The company that I work for is developing a product utilizing uPSD3400 product. I would like to know if there are any examples or drivers for utilizing the USB CDC protocol on a Windows XP platform. I would like to get the DLLs or libraries to include in my LabWindows project, as I am developing a GUI that will communicate to the uPSD application board that my company is devloping. I have not been able to find any drivers other than the demo program which doesnt help me. Thanks for any help I can get regarding this matter.
