+// $Log: /Alaska/SOURCE/Modules/USBRecovery/UsbPeimSrc/UsbIoPeim.c $
+//
+// 6 1/18/11 1:05a Ryanchou
+// [TAG] EIP47931
+// [Category] Improvement
+// [Description] Added USB 3.0 hub support.
+// [Files] EhciPei.c, EhciPei.h, HubPeim.c, HubPeim.h, OhciPei.c,
+// OhciPei.h, UhcPeim.c, UhcPeim.h, usb.h, UsbHostController.h,
+// UsbIoPeim.c, UsbPeim.c, UsbPeim.h, XhciPei.c, XhciPei.h
+//
+// 5 3/17/09 5:04p Olegi
+// Added TransactionTranslator for slow/full speed devices behind USB2
+// hub.
+//
+// 4 3/03/09 7:21p Olegi
+// Changed the type of MaxPktSize from UINT8 to UINT16.
+//
+// 3 7/18/08 5:05p Michaela
+// 1 File-level debugging is now available
+// 2 AMI_USB_DEBUG_INTERFACE.WaitConsoleKey() now returns
+// the keypress so that conditional debugging can
+// be dynamic (alphanumeric keys only)
+// 3 Added more function headers.
+// 4 Removed code that will never be used (I.e., Bala?).
+// 5 Moved typedef, contants and extern declarations
+// into header files.
+// 6 Now all controller blocks are enabled for SB700
+// (EHCI controllers route to companion controller
+// by default)
+// 7 Removed unused constants and typedefs n OhciPei.h
+// (also reorganized the file to make it more
+// readable.)
+// 8 Renamed many functions/variables according to
+// coding standard.
+// 9 Removed code initializing data structures for
+// periodic lists, as this is not needed.
+// 10 Removed the CONTROLLER_TYPE SDL token to
+// allow UHCI and OHCI controllers to supported
+// simultaneously. (modified MAKE files
+// accordingly)
+//
+// 2 7/10/08 6:37p Michaela
+// Updated to support OHCI controllers
+//
+// 1 9/22/06 12:19p Sivagarn
+// - Initial Checkin
+// - Included Recovery code in Source
