This class represents the Java Native Interface to the shared library which
|
| 104 |
|
|
is (with some exceptions) a one-to-one representation of the libusb API.<br>

|
<h1>Project Description</h1>
|
| 107 |
|
|
Java libusb is a Java wrapper for the libusb and libusb-win32 USB library.
|
| 108 |
|
|
|
| 109 |
|
|
<a href="http://libusb.sourceforge.net/">libusb</a> aim is to create a
|
| 110 |
|
|
library for use by user level applications to access USB devices regardless
|
| 111 |
|
|
of OS.<br>
|
| 112 |
|
|
<a href="http://libusb-win32.sourceforge.net/">Libusb-win32</a> is a port of
|
| 113 |
|
|
the USB library <a href="http://libusb.sourceforge.net/">libusb</a> to the
|
| 114 |
|
|
Windows operating systems. The library allows user space applications to
|
| 115 |
|
|
access any USB device on Windows in a generic way without writing any line of
|
| 116 |
|
|
kernel driver code.<br>
|
| 117 |
|
|
<br>
|
| 118 |
|
|
The API description of this class has been copied from the <a
|
| 119 |
|
|
href="http://libusb.sourceforge.net/documentation.html">libusb documentation</a>
|
| 120 |
|
|
and adapted where neccessary.<br>
