My goal is as follows: I would like to build a case that turns my Kobo Clara Colour into a sort of chimera'd Kobo Libra, as far as the physical page turn buttons go. Preferably without adding a second battery or modifying the device hardware directly. I have a 3D printer and a case that I can build off of.
This can alternatively be phrased as "How to use a USB keyboard to control page turning in KOReader on a Kobo Clara Colour," because my initial plan was to use a microcontroller to send keyboard button presses via USB when the page turning keys get pressed. However, I could not find any information about any wired keyboard based solution existing for Kobo devices.
The KOReader github mentions keyboard input is only available for SDL targets, but I'm unsure whether the Kobo is one:

Connecting a keyboard via a powered USB hub didn't do much in the default Kobo ebook reader, KOReader or Plato. I used a powered hub since the kobo doesn't supply power via USB host - another problem I'm unsure of how to solve.
Does anyone know of such a solution, or a reasonable alternative I've overlooked? It would be a stretch to say I'm comfortable with hacking together anything but small microcontroller projects, but I'm happy to learn.
If it is impossible (or implausible) to coerce power out of the USB port, there's a KOReader plugin that instead uses bluetooth:

The main reasons I would rather avoid this is because of not wanting to add a secondary battery, or generally deal with bluetooth shenanigans.
