Android 2.3设备上的USB主机开发
[英]USB Host Development on Android 2.3 Device
问题描述
I just got a development kit that have a physical two USB Host port and the Android specification says it support USB Host, I am curious about this as USB Host is introduced in Android 3.1, where my kit only have Android 2.3 
我刚刚得到了一个具有两个USB物理端口的开发套件，并且Android规范说它支持USB主机，我对此感到很好奇，因为USB主机是在Android 3.1中引入的，而我的套件中只有Android 2.3
Does this mean that I can use the API as described here: 这是否意味着我可以按照此处所述使用API：

No you can't use USB host api in Android 2.3 as USB host mode is supported in Android 3.1 and higher . 不，您不能在Android 2.3中使用USB主机api，因为Android 3.1及更高版本支持USB主机模式。 Even in some of those Device i mean Some Android 3.1 will need root Access to use them in USB Host mode. 即使在某些设备中，我的意思是某些Android 3.1仍需要root访问权限才能在USB主机模式下使用它们。
