USB to ethernet not working on Samsung Galaxy S

Question

I have Samsung Galaxy S Blaze with the following specs

• Samsung Galaxy S Blaze 4G SGH-T769
• Android version = 4.0.4
• Baseband version = T769UVMB1
• Kernel version = 3.0.8-perf-T769ULVH5-CL990184
• Model Number = SGH-T769

I am following this thread on XDA as I had the same problem reported on page 4.

I am using AX88772 compatible USB to Ethernet adapter (pluggable USB 2.0) and have successfully compiled drivers for Android ICS. I have also put the asix.ko into /system/lib/modules directory and loaded it with insmod.

I have connected the Samsung phone with Inateck USB 3.0 four-port hub where I have also connected pluggable USB 2.0 ethernet adapter. But the ethernet is not working:

There is no mention of OTG driver and USB host driver. Are they installed by default? How do I check if I have these installed? Or, are they not needed?

Answer 1

Well, I got the solution. I was using Inateck HB4004G 4-port USB3.0 hub. I should have used an on-the-go (OTG) cable instead. When I used the OTG cable, the ethernet interface eth0 came up.

Here is the OTG cable for your convenience.

Answer 2

Some older USB OTG ports needed a powered OTG. Even powered hubs didn't work on my Motorola Droid 1, whereas that did. Also, some USB Ethernet chips don't work on Android.
