+ * Name: stm32_otghost_initialize
+ *
+ * Description:
+ *   Initialize USB host device controller hardware.
+ *
+ * Input Parameters:
+ *   controller -- If the device supports more than USB host controller, then
+ *     this identifies which controller is being initializeed.  Normally, this
+ *     is just zero.
+ *
+ * Returned Value:
+ *   And instance of the USB host interface.  The controlling task should
+ *   use this interface to (1) call the wait() method to wait for a device
+ *   to be connected, and (2) call the enumerate() method to bind the device
+ *   to a class driver.
+ *
+ * Assumptions:
+ * - This function should called in the initialization sequence in order
+ *   to initialize the USB device functionality.
+ * - Class drivers should be initialized prior to calling this function.
+ *   Otherwise, there is a race condition if the device is already connected.
