USBInfo version

USBInfo provides Python developers a way to uniformly access information about USB endpoints on a system without the need to understand the fine details of any one particular platform's implementation of USB. This is useful in robotics and device automation and allows developers to write more portable code.

Installation

This version of USBInfo requires Python 2.6 or above running on a POSIX-compliant system.

USBInfo is on PyPI and can be installed using:

pip install usbinfo

Invocation of usbtool command line tool

The usbtool allows for gathering of information of endpoints on the USB subsystem from the command line. When invoked without any arguments, usbtool prints a tabular representation of attached USB endpoints:
