       usb_gadget_disconnect - software-controlled disconnect from USB host


       int usb_gadget_disconnect  (struct usb_gadget * gadget);


       gadget the peripheral being disconnected


       Disables the D+ (or potentially D-) pullup, which the host may see as a
       disconnect (when a VBUS session is active).  Not  all  systems  support
       software pullup controls.

       This  routine may be used during the gadget driver bind call to prevent
       the peripheral from ever being visible to the USB  host,  unless  later
       usb_gadget_connect  is  called.  For  example, user mode components may
       need to be activated before the system can talk to hosts.

       Returns zero on success, else negative errno.
