I have the newest eclipse & Android SDK -release 11- installed on Windows Vista. I updated the SDK and chose Android 3.0.1. I connected an Android 3.01 Acer Iconia Tab A500. Installed the original Acer USB driver. The Iconia shows up in Windows and I can connect to the Iconia's file system. In Eclipse / DDMS no devices are shown in the list. Kind regards, Tony Thijs
If you are using Ubuntu,
Firstly, add your USB vendor ID to the file 51-android.rules
. See here for more details.
Next,
sudo ./adb kill-server
sudo ./adb start-server
Also make sure that your USB Debugging is enabled in the device.
