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.

Requirements:
- 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:

USB主机诊断决定了你的设备的USB主机功能。

USB主机是近期基于Android的智能手机和平板电脑的一个非常强大的功能,但在许多固件(包括股票和自定义)的特点是有点破。

例如,在推出的Galaxy Nexus的告诉所有的应用程序,它支持USB主机,但USB主机没有实际工作(这是固定在Android 4.0.2更新)的市场。这打破了几个应用程序。

这仅仅是一个很多的例子。甚至有情况下,OEM厂商做广告USB主机支持,但该设备不支持它。它看起来好像当他们推出新的固件和设备在所有USB主机支持没有被谷歌或原始设备制造商进行测试。

正如我们不能依赖于谷歌或OEM厂商能够提供正确的信息有关USB主机支持,Android框架会经常撒谎到两个市场以及Android应用程序,该应用程序的创建,以便可以测试设备的USB主机功能为自己。

如果允许的话,应用程序也将提交结果到我的网站,让我们一起可以创造设备和固件及其USB主机支持的一个完整的数据库。

该工具还可以派上用场,对于那些移植固件。

要求:
- 安卓2.3.1或更高版本
- (可选)根
- USB OTG连接线(除非你的设备具有全尺寸USB端口)
- USB记忆棒,或其他USB设备来测试与连接
