  Enable high speed support for USB device framework and usbtty

 			Define this to have a tty type of device available to
 			talk to the UDC device
 
+			CONFIG_USBD_HS
+			Define this to enable the high speed support for usb
+			device and usbtty. If this feature is enabled, a routine
+			int is_usbd_high_speed(void)
+			also needs to be defined by the driver to dynamically poll

 			CONFIG_SYS_CONSOLE_IS_IN_ENV
 			Define this if you want stdin, stdout &/or stderr to
 			be set to usbtty.
