libusb

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku, Solaris userspace, and WebAssembly via WebUSB. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).

libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
