usb require is not defined

It seems like you're experiencing an error message saying "usb require is not defined." This error typically occurs when attempting to use the 'usb' module or function without properly importing it in your code.

To resolve this issue, make sure you have imported the 'usb' module at the beginning of your script. You can do this by adding the following line of code:

import usb

If you have already imported the module and still encountering the error, ensure that you have installed the 'usb' module correctly. You can install it using a package manager like pip:

pip install pyusb

Make sure you have an active internet connection and run this command in your command-line interface.

If the problem persists, please provide more details about your code and the specific steps you've taken so far, so I can assist you further.
