Odroid N2l is not communicating via USB 3.0. A mouse, keyboard, and HDD have been tested. Power supply to the port is working.
I tried it all 3 build of CoreELEC for Odroid N2l (boot from SD card)
My N2l has 4GB RAM
As I said on odroid forum, I have no problem with USB ports on latest nightly, wifi dongle is working and a USB stick was mounted.
