For some reason ADB can't find my S4 although I'm the opinion that I've done everything:
-Added my hardware id to android_winusb and adb_usb
-Enabled USB-debugging
-Changed USB ports
-Rebooted several times
-Installed Kies
-Installed google driver via driver manager
My OS: Win 7 x64
Additionally: the device manager shows my mobile twice: once in 'Other devices' as SAMSUNG_Android and once as [hostname] in 'Portable devices'
Have i forgotten something?
New information:
Now I know that the issue has to do with my pc software configuration.
Try this Samsung universal adb driver http://download.clockworkmod.com/test/UniversalAdbDriverSetup6.msi
Sometimes you just need to deactivate and reactivate USB debugging to work too.
