    The Aspeed AST2500 SoC contains a number of USB controllers:
    
    * USB 1.1 Host Controller
    * USB 2.0 Host Controller (x2)
    * USB 2.0 Virtual Hub
    * USB 2.0 Device Controller
    * USB 1.1 HID Controller
    
    The controllers are exposed via two USB ports with functionality muxed
    as required. The following table illustrates the relationships between
    the ports and the controllers via the mux function names:

    ------|--------------|--------------|-------------
    A     | 2.0          | Virtual Hub  | USB2AD
    A     | 2.0          | Host         | USB2AH
