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