This won't work it you build CONFIG_USB_EHCI_HCD_PMC_MSP and other ehci
controller.
A better alternative could something like :
http://article.gmane.org/gmane.linux.usb.general/42624
+
+/* host mode */
+#define USB_CTRL_MODE_HOST 0x3
+
+/* big endian */
+#define USB_CTRL_MODE_BIG_ENDIAN 0x4
+
+/* stream disable*/
+#define USB_CTRL_MODE_STREAM_DISABLE 0x10
+
This doesn't seem to be used anymore.
