     14  The ASPEED USB 2.0 Virtual Hub Controller implements 1 set of USB Hub
     15  register and several sets of Device and Endpoint registers to support
     16  the Virtual Hub's downstream USB devices.
     17
     18  Supported number of devices and endpoints vary depending on hardware
     19  revisions. AST2400 and AST2500 Virtual Hub supports 5 downstream devices
     20  and 15 generic endpoints, while AST2600 Virtual Hub supports 7 downstream
     21  devices and 21 generic endpoints.
