USB_GADGET_WAKEUP(9) Kernel Mode Gadget API USB_GADGET_WAKEUP(9)
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.
