How Do I Communicate With A USB Scanner?

Question

I'm building an application in C++, that will be deployed on Windows. I kind of got thrown into this, and I've managed to make my way through 80% of the project requirements, but I'm having a hang up on one of the requirements:

I need to interface with a Business Card Scanner on a USB port. Is there a standard way of doing this, and if so, can someone give me a list of steps I need to take?

The thing is built on the Qt Framework, if that makes any difference.

Thanks, Goldentoa11

Answer 1

C++ Wrapper for TWAIN is a good start, it's an MFC exampel but the base class is simple enough.

(assuming the scanner supports TWAIN of course !)
