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:

root@hammerhead:/ # netcfg eth0 up
netcfg eth0 up
action 'up' failed (No such device)

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?

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.


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.
