<title>Overview</title>
<para>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 <ulink url="http://libusb.sourceforge.net/">libusb</ulink> website to see if it is stable and recommended.</para>
<para>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 <ulink url="http://www.usb.org/developers/docs/usbspec.zip">v1.1</ulink> and/or <ulink url="http://www.usb.org/developers/docs/usb_20.zip">v2.0</ulink> specs and read them.</para>
<para>libusb is geared towards &usb; 1.1, however from the perspective of libusb, &usb; 2.0 won't be a significant change for libusb</para>
