adb not working in the GS290 /e/recovery

• /e/ version: latest version of the test branch
• Device model(s): GS290

Summary

The problem

Steps to reproduce

What is the current behavior?

I wanted to flash the stable build through the recovery (with the "Apply update" > "Apply from ADB" feature) but my computer doesn't detect any device when I launch adb devices.

I also tried "Advanced > Enable ADB".

No problem when I'm on /e/OS.

What is the expected correct behavior?

The device should be detected by adb devices and we should be able to sideload.
