usb_gadget_vbus_connect - Notify controller that VBUS is powered
int usb_gadget_vbus_connect (struct usb_gadget * gadget);
gadget The device which now has VBUS power.
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.
