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.
If you are using Ubuntu,
Firstly, add your USB vendor ID to the file
51-android.rules. See here for more details.
sudo ./adb kill-server sudo ./adb start-server
Also make sure that your USB Debugging is enabled in the device.
Have you made sure “USB debugging” is enabled on the device?
Settings >> Applications >> Development >> USB debugging
If You are using windows manually end process of adb.exe. Pres Ctrl+alt+Del find adb.exe and press “end process”.
After that execute
adb start-server on your command promt.
I did those things and it solved the problem. Hopefully it can also solve your problem.
I’m using ubuntu 10.10 alongside a500. The instructions from the link and sudo commands helped. I also tried without sudo and that didn’t work (got ????? in adb devices). Please note that for my dev I’m using eclipse running under a normal account. Below is my output from “adb devices”
android-sdk-linux_x86/platform-tools$ ./adb devices
List of devices attached
