I have a HID device (magnetic cardreader) that uses a usb port to connect to a computer running any version of windows. &nbsp;I want to be able to figure out what port the device is on and read information from it. &nbsp;I know I need to use the Win32 API, but I haven't been able to find any useful information on how to do this. &nbsp;Can any one help? <br />

Thanks in advance.

Reading from a USB port with Win32 API

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
