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.
