RTFM

I've recently been helping my son to learn to code in Python.

I've also bought a portable scanner so I can scan documents and add them to Paperless which is running on my homelab.

I've been explaining to my son why he needs to read the error messages to understand why something isn't working, such as a syntax error or an undefined variable.

After plugging in my scanner and wondering why it wasn't showing in the gscan2pdf application, I found a switch to toggle an auto start setting.

If auto start is enabled, the scanner only works with its own software.

Once I disabled it, the scanner appeared.

Here's the thing

Both of these situations were solved by doing the same thing.

RTFM.
