Open Network Preferences
Select the location you will be using
Select the USB Ethernet
Click the - sign at the bottom of the left column to remove
Click the + sign at the bottom
Interface: USB Ethernet
Now the USB Ethernet is back... try that and see if it refreshes anything.

I tried this procedure many times and also tried to create a new location and add the device, but no success.
Thanks for the reply rvaro2

Have you tried cycling both pieces of equipment off and then back on again?

I tried to cycle both pieces and it didn't work. I also tried a PRAM reset.

First of all I'd like to Thanks the Apple phone support. I really apreciate your attention.
We tried a lot of stuff ( PRAM reset, Removing USB config, Creating new network location, restoring using the time machine) none solved my problem
At the end I decided to restore my macbook air from scratch. I don't know why, but Montain Lion Recovery also failed so I was instructed by support to run a Internet Recovery (Command + Option + R). Few hours later my USB Ethernet is back to work.
Now I have to waste my time copying back my files and reinstall all apps.
We could define if the problem is the Samsung or Android apps, but anyway I'll not install this crap on my Mac again.
If you are a Samsung SIII owner like me, install that software in a virtual machine or do not think in sync it with your mac.

I have exactly the same problem, also after installing Kies.
I DO NOT want to have to wipe my machine to solve it! Has anyone else come up with a less drastic solution, or any further understanding as to what the actual problem was?

Thank you rvaro2
This worked for me perfectly.
My Ethernet stopped working when I plugged the Ethernet in using a thunderbolt adapter. I got a warning on the screen and the Mac shut down....I guess the equivalent of a Windows Blue Screen!
Anyway, your recommendation worked, and my Ethernet is back.

I had the same problem, no ethernet lights flashing and no
My solution was to select the USB ethernet adapter from
System preferences -> network
In Advanced, select
Renew DHCP Lease
Instantly all was OK.
