| * Compile and flash this firmware onto a ESP32-S2 and then use a seperate micro USB connector | |
| * to connect the S2's Pin 19 to USB D- and Pin 20 to USB D+ (and of course +5V to +5V and GND to GND) | |
| * | |
| * IMPORTANT: On an ESP32-S2 Mini using Arduino IDE, make sure you have 'USB CDC On Boot' set to 'False' | |
| * otherwise the 'USB Device Name' that shows up on Windows will not be correct as per the code below. | |
| * | |
| * It will appear as a 'USB Mouse' in Windows/Linux/Mac, and move the mouse every 30 seconds or so | |
| * that you are always online/green. The ESP's LED will flash briefly when this occurs. | |

Calibre is a powerful cross-platform, open source, ebook manager and editing platform. Its calibre-server component can be used to publish an e-book library on a local network. While you can launch calibre-server as a desktop application, it can also be run as a daemon on a headless Linux server.
This tutorial on setting up calibre-server using Ubuntu 14.04 is very good, but dated.
