HIDAPI is a multi-platform library which allows an application to interface with USB and Bluetooth HID-Class devices on Windows, Linux, and Mac OS X. On Windows, a DLL is built. On other platforms (and optionally on Windows), the single source file can simply be dropped into a target application. HIDAPI has four back-ends: * Windows (using hid.dll) * Linux/hidraw (using the Kernel's hidraw driver) * Linux/libusb (using libusb-1.0) * Mac (using IOHidManager) This package includes only the libusb backend.
