   2 // The EhciDxe driver is responsible for managing the behavior of EHCI controller.
   3 //
   4 // It implements the interfaces of monitoring the status of all ports and transferring
   5 // Control, Bulk, Interrupt and Isochronous requests to Usb2.0 device.
   6 //
   7 // Note that EhciDxe driver is enhanced to guarantee that the EHCI controller get attached
   8 // to the EHCI controller before the UHCI driver attaches to the companion UHCI controller.
   9 // This way avoids the control transfer on a shared port between EHCI and companion host
  10 // controller when UHCI gets attached earlier than EHCI and a USB 2.0 device inserts.
