I am trying to debug my application using a real device instead on the emulator. When I try to connect, it gives me the message:
USB device not found<
Found out for Samsung, Installing Kies also update the usb driver which solve my problem with connecting my Samsung Galaxy S Advance with Android 4.1.2 to Android Studio on Windows 7 64bit. In this case the devise manager shows device driver is updated and working, but when I connect my phone Android Studio does not recognize my device.
