Lots of people are facing this problem and having issues that their device are not getting recognized by adb manager or through adb devices in cmd.
Follow these steps and get your development device connected:
Launch your Android SDK Manager and check whether your "Google USB Driver Package" is installed or not. If it is not installed then install it first otherwise the required driver will be missed.
Then for XP Users:-
- Connect your Android-powered device to your computer's USB port(Make sure that you enable USB debugging mode in your device which you will find under Settings > Applications > Development OR Settings > Development Options.). Windows
will detect the device and launch the Hardware Update Wizard.
- Select Install from a list or specific location and click
Next.
- Select Search for the best driver in these locations; un-check
Search
removable media; and check Include
this location in the search.
- Click Browse and locate the USB driver folder. (Locate the Google USB Driver under
"<path_to_your_sdk>\extras\google\usb_driver\".)
- Click Next to install the driver.
Hopefully it will work...........and you are good to go........
