For KB920X boards the USB2 is enabled by default. It is not much you need:
+device usb2_core
+device usb2_controller # EHCI/OHCI/UHCI/AT91DCI
+device usb2_storage # USB mass storage support
+device usb2_ethernet # USB ethernet support
+device usb2_wlan # USB wireless LAN support
+device usb2_serial # USB serial support
+device usb2_quirk # USB quirks
+device usb2_template # Device Side Mode USB templates
+device usb2_image # USB Scanner support
