Help replicating USB device on esp32 S2 mini - Change USB configuration

[Boom123bam]

Hello,
I’m trying to replicate a USB device (3Dconnexion SpaceMouse) using an ESP32-S2 Mini.
I’ve managed to get it to show up as a genuine SpaceMouse; however, I’m struggling to send any commands.


I’ve found that the USB configuration is not the same.

In the image below, the left side is what I have, and the right side is the SpaceMouse that is working. The Interfaces seem to be in the wrong order, how can I change them to match the original?




This is the code I am referencing, it is made for a pro-micro, so I am trying to convert it for esp32 https://github.com/AndunHH/spacemouse/b ... MouseHID.h
Below is the main file, but the whole repo can be found here https://github.com/Boom123bam/esp32-s2mini-spacemouse
