USB_COMPOSITE_PROBE(9) Kernel Mode Gadget API USB_COMPOSITE_PROBE(9)NAMEusb_composite_probe - register a composite driver
SYNOPSIS
int usb_composite_probe(struct usb_composite_driver * driver);
ARGUMENTS
driver
the driver to register
CONTEXT
single threaded during gadget setup
DESCRIPTION
This function is used to register drivers using the composite driver
framework. The return value is zero, or a negative errno value. Those
values normally come from the driver's bind method, which does all the
work of setting up the driver to match the hardware.
On successful return, the gadget is ready to respond to requests from
the host, unless one of its components invokes usb_gadget_disconnect
while it was binding. That would usually be done in order to wait for
some userspace participation.
