USB in Visual C++

[Johnny Peszek]

Hi. How to use Visual C++ to create a program for Input/Output via USB port? Many thanks for help.

What do you mean exactly when you say: 'via USB Port' ? Are you using a USB-To-Serial adapter or another USB device ? Fir the second case, a driver is shipped with the device and there shoulb documentation included. You must open the port using the CreateFile function specifying the name of the device you want to access. Then you use the DeviceIoControl function to send command to the driver. Hope this helps

I participate in a project in which I have to establish comminication betwen Digital Signal Processor and PC via USB. This is the beginning of the project and we don't know that DSP would be the best. I will give more information as soon as the specification of the project is more clear. Thanks!
