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.
