NAME

       usb_gadget_wakeup - tries to wake up the host connected to this gadget

SYNOPSIS

       int usb_gadget_wakeup  (struct usb_gadget * gadget);

ARGUMENTS

       gadget controller used to wake up the host

DESCRIPTION

       Returns  zero  on  success,  else  negative  error code if the hardware
       doesn’t support such attempts, or its support has not been  enabled  by
       the  usb host. Drivers must return device descriptors that report their
       ability to support this, or hosts won’t enable it.

       This may also try to use SRP to wake the host  and  start  enumeration,
       even  if  OTG isn’t otherwise in use. OTG devices may also start remote
       wakeup even when hosts don’t explicitly enable it.
