CDD: USB mass storage class req for AOAP
USB host machines that supports both AOAP and generic USB mass
storage devices, might send AOAP commands and cause some USB mass
storage devices to enter a wrong state.
This requirement is expected to allow such host machines to
implement a mechanism to avoid such interoperability issues.
Bug: 22041890
