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.

I had this problem occurring suddenly in Dell Ubuntu linux machine with Android Developer Studio. I did the following steps

    1. I opened "System Settings"
    2. Select the listed item "Software and Updates"
    3. Click on the tab "Additional Drivers"
    4. There was a mention about "Dell Inc: Unknown" and the option "Do not use use the device" selected. I selected the alternate driver mentioned and did an "Apply the Changes".

It started working.
