Qt Creator doesn't find my Android device

Question

The steps I've taken so far are:

1. Downloaded qt-opensource-windows-x86-android-5.3.0-RC.exe from http://download.qt-project.org/development_releases/qt/5.3/5.3.0-rc/ and installed it.
2. Downloaded the Android SDK, etc., according to Creator's Android Configurations dialog:
3. Ran my application. A dialog came up saying Device not found, and suggesting that I run adb devices to see if the device is indeed available. I ran that, but no devices were connected.

Answer 1

After reading this blog post, I found out that it was necessary to install Google's USB Driver that was downloaded when I ran the SDK Manager. The instructions for doing so are here.
