i would like to allow my tablet Teclast T20 to connect to ETHERNET via USB.
I already own a USB to ETHERNET ADAPTER, that i use succesfully with my windows 10 laptop.
It is an ASIX AX88772 USB2.0 to Fast Ethernet Adapter, and i found that for this adapter is available a driver (source) in ASIX website
ASIX AX88772 USB2.0 to Fast Ethernet Adapter Drivers
that should work for Linux and Android.
But when i connect the adapter to my tablet using an OTG Usb to microusb cable, and connect the ethernet cable to the adapter, nothing happens.
Searching on the web, i found that with Teclast T10, that is and older version of my tablet (that was without 3G module), was possible to connect to ethernet via a similar adapter with same chipset as mine : UtechSmart USB 2.0 to 10/100 Ethernet Network Adapter (Model US-USB2-E100). Take a look here (min 5:55) Video
My tablet Teclast T20 has cpu MT6797X (X27) and runs on Android Nougat 7.1 and has connectivity WiFi + LTE The Teclast T10, instead, has cpu MT8176 and runs on Android Nougat 7.0 and has only WiFi connectivity
So perhaps the kernel is different and the drivers pre-built in the kernel are different. How can i check if an USB to Ethernet driver is already built in the kernel of my tablet? And, if it is not available, how can i add the driver to my tablet? I know that i should have the sources of my kernel, but i think it will be difficult to get them from Teclast. Any suggestion?
Thank you! Lodovico.
dmesg) when you plug in the USB Ethernet adapter if it has been loaded correctly. The main problem is that usually you would execute the dmesg command via ADB/USB but the port is required for the Ethernet adapter. Therefore I would try to use ADB over Wifi to establish an adb connection that does not block the USB port. Then connect the USB Ethernet adapter and check the dmesg messages. I did this just for testing and was able even to see the link up/down messages. – Robert Nov 13 '19 at 13:07
