Ethernet support

I´m trying to conect to the Internet through a ethernet/giganet USB to RJ45. It allows direct conection from the router to the phone.

You need root, and OTG support (RMN2 ok), ethernet apk from google play.

I´ve used with MotoG (qualcom SD400, android 5.0.2), MiPad (nvidia tegra K1, android 4.4.4), and Pipo P1 (rockchip, android 4.4.2) and perfect.

But I can´t used it with this Mediatek Helio X10, android miui 5.02....?¿?¿

I installed busybox, mediatek uncle tools, etc. but It still doesn´t worx....

Any idea, suggestion?¿?¿?

Thanks!
