Dear all,


My Macbook air (late 2011) USB Ethernet adapter stopped to work after I installed Samsung Kies and Android File Transfer. I already removed the apps and the USB continues to not work.
In System Report (About this mac -> More information) in the USB tab shows the device working with no problem, there is no USB issue, I already plugged other devices (USB HD for Time Machine and my iPhone). I also tested the cable and the USB Ethernet adapter and it works fine in other Macbook air.

I tried to remove the service and add it again and it keeps showing Cable Unplugged.

I upgraded my mac from Lion to Montain Lion trying to solve the issue, but no success and tried DHCP and Fixed IP in the config.
Does anyone have a clue of the issue or know a way to reinstall the USB drivers to fix this problem?





MacBook Air, OS X Mountain Lion (10.8.1)
