I am trying to hack my EV3, and I know I can make it execute commands I send via USB thanks to the communication developer kit.

When I connect it via USB, it is only visible by the MINSTORMS Home app and the system report (I am on Mac).

When I try to list serial ports, with for example ls /dev/tty.*, the EV3 doesn't show, which means I can't connect to it.

However, if their app does it, then there is a way around. Has anyone encountered this before, or does anyone know how their app does it?

The Bluetooth connection appears as a serial port, but USB does not. Instead USB on the EV3 appears as an HID device. So you will need a library that provides low-level (raw) access to HID devices.
