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.

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.
