NAME
       usb_gadget_vbus_connect - Notify controller that VBUS is powered

SYNOPSIS
       int usb_gadget_vbus_connect(struct usb_gadget * gadget);

ARGUMENTS
       gadget
	   The device which now has VBUS power.

CONTEXT
       can sleep

DESCRIPTION
       This call is used by a driver for an external transceiver (or GPIO)
       that detects a VBUS power session starting. Common responses include
       resuming the controller, activating the D+ (or D-) pullup to let the
       host detect that a USB device is attached, and starting to draw power
       (8mA or possibly more, especially after SET_CONFIGURATION).

       Returns zero on success, else negative errno.
