Use the Human Interface Device (HID) module

The Python hid module provides a programmatic access to a USB Human Interface Device (HID) from
within a Python script.
For example, to determine information about a USB-connected keyboard:
1. Log into the TX54 command line as a user with shell access.
Depending on your device configuration, you may be presented with an Access selection
menu. Type shell to access the device shell.
2. At the shell prompt, use the python command with no parameters to enter an interactive
Python session:
# python
Python 3.6.13 (default, May
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
