Hi,
I need to communicate with a board using USB protocols and I was wondering if anyone has done this before and could point me in the right direction as to how I can get started with that. I looked online but could not find anything regarding making a program, using available drivers or otherwise. I will be using Windows 2000 with VS .NET 2003. Thanks a lot,
Amish
I have read the msdn help files and searched on google but they don't tell you how to actually get started with a program. That's what i need to know. Thanks for the info though

Well, to get started, just try to connect to a USB port. If you connect, send/recieve data, then close the port.Quote:

What I want to do is write a small program that blinks the light on a usb keyboard and maybe receives characters also. I looked at the msdn website but was stumped when I reached this page:

Where do I get USB_HANDLE hDevice from. It does not say anything about that. Thanks for you help

Pick up the device driver sdk (i'd post a link but i'm not at home). Also, you know there are easier ways of just making the led blink right? You are trying to use low level calls for something windows has included in its higher level API. Are you writing a DOS program?
Well this is just a start. I will eventually want to do some more advanced communication with other usb devices. That's why I want to start with the low level stuff. My application will be a win32 application. Can you elaborate on the Device Driver SDK. What is it exactly?

This USB library list may help you.
Thks i'll look into those links today
