I updated Kies today and my Samsung Galaxy S2 phone doesnt connect to my pc via Debug Mode any more.
Below is the screen shot
When i uninstall that and try to reconnect i get an error saying driver instal failed.
Right-click on that "SAMSUNG_Android" and select
If you are on Windows 7 64-bit, you may be able to bypass Kies software by installing this driver (remove the "SAMSUNG_Android" from Device Manager again before installing the driver.)
