adb devices list empty on Toshiba AS100 tablet

I'm running into an issue with the android SDK where it doesn't recognize devices (Toshiba AS100) under windows, adb devices list is empty:

$adb devices                                      
List of devices attached

Have tried:

• Tutorial: "Enable ADB USB Drivers for Nvidia Tegra based Android Tablets"

• Setting: Settings --> Applications --> Development --> USB Debugging

According to the tutorial, it works on HTC & Toshiba AC100, but failed on Toshiba AS100. I can find "Android Phone" "Android Composite ADB Interface" items under &qu开发者_JAVA技巧ot;Device Manager", but the adb devices list is still empty. Is there an solution to this problem? Thank you.

Check here,

My device was not detected in Ubuntu , changed the rules , it worked fine. In windows , it says USB driver should be installed. So there might be the issue.

It works! I removed all the emulators and restored all run configures to default. With a third-party usb adb driver, eclispe finds the device automatically. However,it cannot work when sdk's adb running, and cannot show in devices list. Thanks...
