USB Class on android

Where is the USB class support implemented in Android devices, is it on the ANDROID version, or the chipset level?

In other words if I want to know if a specific smartphone supports for example UVC class, would I need to check the chipset or the Android version to know the answer to this?

The official way to determine if the device has USB host capability is to use the associated system feature.

Ideally, add a <uses-feature> element to your manifest, indicating that you are interested in the android.hardware.usb.host feature. If you do not absolutely need that feature, add android:required="false" as an attribute.

If you went with android:required="false", and you want to determine whether the device is a USB host at runtime, use PackageManager, hasSystemFeature(), and FEATURE_USB_HOST. FEATURE_USB_HOST is defined as the same string as you would be using in <uses-feature> (android.hardware.usb.host).
