IDE does not display target device

Hi All,

I'm trying to deploy Tasky application into my Samsung Galaxy 10.2 using Visual Studio 2012 and Xamarin

Device: Samsung Galaxy Tab 2 10.1 Android version: 4.1.1 Kernel Version 3.0.31-523998 USB debugging is enabled Tablet is connected to the computer by USB Cable.

I already ran adb kill-server and adb start-server When I run adb usb result is "device not found" When I run adb devices returns empty list. I already restarted visual studio 2012 Android SDK 4.0.3 (API 15) installed on my pc. Google USB driver installed.

Thanks for your help.
