libusb is used for driving the USB control data endpoints instead of the Linux HID driver for distribution compatibility reasons. The following section describes the minimum libusb requirements for running Tux Droid Daemon and developing Tux Droid programs using libusb. Useful links are provided for troubleshooting if needed.

libusb requirements

Tux Droid applications require:

• the libusb version 1.8 or higher
  

Development of Tux Droid applications controlling the Tux hardware through libusb requires:

• libusb-devel version 1.8 or higher
  

libusb installation status

You may check if ALSA is installed by typing in a terminal the following command:

$ whereis libusb
libusb: /usr/lib/libusb.la /usr/lib/libusb.a /usr/lib/libusb.so

Using libusb with Tux Droid

Documentation and the source code can be found at libusb project home.

The easiest way to understand libusb is to read the Tux Daemon documentation and source code. It describes the conversion between high level TCP/IP requests and basic libusb equivalents (Tux Droid Services)
