Android device does not show up in adb list

Looks like the installed driver was in bad state. Here is what I did to make it work:

  1. Delete the device from Device Manager.
  2. Rescan for hardware changes.
  3. List item “Slate 21” will show up with “Unknown driver” status.
  4. Click on “Update Driver” and select /extras/google/usb_driver

Device Manager will find the driver and warn you about installing it. Select “Yes.” This time the device got installed properly.

Note that I didn’t have to modify winusb.inf file or update any other driver.

Hope this helps.
