Answer 1

Try pre-installing the drivers for your devices. Make sure, under Windows, that your device is recognized in the System control panel first.

I use Windows 7 and my Galaxy Nexus wouldn't be recognized by the system until I installed the device drivers before plugging them in. From the comments, this works on Windows 8 as well.

• Goto Manual & Drivers > Software

Answer 2

Just though Id share my experience, I had -

• Unplugged and re plugged in the device
• Installed the correct platform tools
• Installed the correct Android bridge Turned USB debugging on and off and on and off an...
• Tried WiFi but it said it was offline
• etc. etc.

What fixed it for me was changing the device connection from Mass Storage to MTP. To do so, with the phone unplugged you go into -

"Settings" -> "Storage" -> Click the menu Button -> "USB computer connection" -> "Media device (MTP)"

Hope this helps some one from going crazy!

Thanks,

Ash.

I had this problem today and fixed it by rebooting the Tab2 while leaving it plugged into the laptop/eclipse

Answer 4

It's working on windows 8 using Android 4.4.2

Reset your phone,

• go to setting->about phone-> seven time click on build number.
• go to back and go to developer options check USB debugging.
• go to windows 8 start menu click on profile picture and click change profile picture.

Select devices and on Download over metered connections. Connect your phone via cable your PC and wait.

Answer 5

Here is what I did (Galaxy S4 4.2.2):

• go to Settings => about this device => click several times on "Version number", that is to say something like "JDQ39.I9505XXBHYTGKDD" (not android version or anything else) ; here you will see that Google or Samsung have a lot of humour as you have to click until multiple times until having a toast displaying "You are at few clicks from being a developer" ; after something like 10 clicks, you have a toast "You are a developer"

• Go "Development options" (in the "More" tab (rigjt tab of settings menu)) ; be sure that "USB debugging" is checked.

And it works ! Eclipse can see your S4(or any other device) 4.2.2 !

Answer 6

You may use an old version of adb.exe. Update platform-tools. You may have to set a new path to adb.exe as well.
