Android ADB USB Interface Types

A previous post mentions when you install a USB driver on windows a pop-up shows three options of interface types. While looking into the inf file there are three interfaces: 

SingleAdbInterface          = "Android ADB Interface"
CompositeAdbInterface       = "Android Composite ADB Interface"
SingleBootLoaderInterface   = "Android Bootloader Interface"

Are there any documents or descriptions of the protocols or features on these interface?

Solution

  • In Windows ADB uses the generic WINUSB driver. The adb binary handles the protocol all by itself.
