UsbHidApi USB Comm Library

This DLL (and demo application) provide API functions that encapsulate the complexity of Windows USB access so you can focus on writing the host application itself instead of the details of USB operation. You get easy access to your device using simple Open(), Read(), and Write() functions. The included demo application shows you how. Demo app source code and project files are also included [VC++]. No custom drivers are needed; it uses existing Windows drivers. Only for USB HID (Human Interface Class) devices.
