ethernet usb not recognized with adalm pluto

Hi,

I have an Ethernet usb adapter like this:

https://www.amazon.es/AmazonBasics-Adaptador-red-LAN-Ethernet/dp/B00M77HLII/ref=sr_1_29?ie=UTF8&qid=1525853686&sr=8-29&keywords=usb+ethernet

but for some reason when I plug this device to the pluto usb througth and OTG cable with an usb power connected to the other usb for powering the pluto the ethernet adapter doesn't turn on(green led is OFF) and do nothing.

I don't know what to do because with this device connected to usb I can't go inside pluto to see if device is recognized or not.

the adapter is working correctly with usb 2.0 in a windows machine.

I tried to use a usb hub for powering the adapter with an external power source but nothing.

Any ideas?.

thanks.

    usbcore: registered new interface driver ax88179_178a

    Is kind of meaningless, it only says it has registered a driver. The USB OTG controller operates as Dual Role Device (DRD). The is USB OTG spec defines two protocols  HNP, SRP.

    Please take a look here at this very good tutorial: USB On-the-Go Basics 

    The Pluto supports the HNP, it's therefore important to use a micro-AB adaptor with the ID pin grounded, when a USB Device such as WIFI, USB Memory, etc. is connected to the Pluto.

    Once the USB stack has determined that it must act as a USB Host - it will print the HUB found stuff besides a few other messages.
