Mi Box USB-RJ45 adapter not working

Hi, I bought a Mi Box model MDZ-16-AB this week.
Everything works fine, except ethernet.
I use an RANKJE (ijetch.com) R-1161-ADAPTER-USB3.0-RJ45-BK/B13
but only wifi if proposed, not ethernet.

No ADB debug or USB Debug is activated, not any debugging options actived (but I enable dev mode to verify).
Android version 6.0.x
A solution ? Thanks a lot.
