+# 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.

+# 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.
