This documentation will give an overview of how the v0.1 libusb API works and relates to &usb;. Work is rapidly progressing on a newer version of libusb, to be v1.0, which will be a redesigned API and is intended to obsolete v0.1. You may want to check the libusb website to see if it is stable and recommended. This documentation assumes that you have a good understanding of &usb; and how it works. If you don't have a good understanding of USB, it is recommended you obtain the USB v1.1 and/or v2.0 specs and read them. libusb is geared towards &usb; 1.1, however from the perspective of libusb, &usb; 2.0 won't be a significant change for libusb Linux (2.2, 2.4 and on) FreeBSD, NetBSD and OpenBSD Darwin/MacOS X
