    USB Host Diagnostics determines your device's USB host capabilities.

    USB host is a very powerful feature of recent Android based smartphones and tablets, but on many firmwares (both stock and custom) the feature is somewhat broken.

    For example, at launch the Galaxy Nexus told all the apps and the Market that it supported USB host, but USB host did not actually work (this was fixed in the Android 4.0.2 update). This broke several apps.

    That is just one example of many. There are even cases where OEMs advertise USB host support, but the device does not support it at all. It appears as if USB host support isn't tested by Google or the OEMs when they push out new firmwares and devices at all.

    As we cannot depend on Google or the OEMs to correctly provide information regarding USB host support, and the Android framework will regularly lie about it to both the Market as well as Android apps, this application was created so you can test your device's USB host capabilities for yourself.

    If you allow it, the app will also submit your results to my website, so together we can create a complete database of devices and firmwares and their USB host support.

    This tool may also come in handy for those porting firmwares.

    - Android 2.3.1 or newer
    - (Optional) Root
    - USB OTG cable (unless your device has a fullsize USB port)
    - USB memory stick, or another USB device to test the connection with

    The result database is available here:

    Too technical with all the details, you need an expandable summary, and ability to save results without retesting
