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
9 2021, 22:49:59)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
3. Import the hid module:
>>> import hid
>>>
4. Use the enumerate() function to return information about the keyboard:
>>> hid.enumerate()
This returns the following:
[{'path': b'/dev/hidraw0', 'vendor_id': 1008, 'product_id': 36, 'serial_
number': '', 'release_number': 768,
'manufacturer_string': 'CHICONY', 'product_string': 'Basic USB Keyboard',
'usage_page': 18432, 'usage': 17481,
'interface_number': 0}]
