I have the samsung galaxy tab, when I plug it into to eclipse to run and debug my apps. Eclipse doesn\'t recognize the device. When I try it with my friend\'s Droid 2 it sti
Ι had the same problem:
While i had activated the debugging options on my phone (Samsung Galaxy S Duos Black), eclipse couldn't find the device because the usb drivers failed to download or something and so in the Device Manager (win7) i saw only Android and CSC something, all yellow and with no installed drivers.
I tried to download the Samsung drivers manually, but this failed to work.
What REALLY worked was downloading+installing Samsung Kies, connecting my device through usb and at first it failed again to put the drivers, then i disconnected the device, pressed some troubleshooting errors button that was on the main screen (NOT the lite version, the normal one), that took some time, re-connected the device and voila, the drivers were installed successfully and both the Device Manager and eclipse recognised the device.
