NAME¶
usb_composite_probe - register a composite driverSYNOPSIS¶
int
usb_composite_probe(struct usb_composite_driver * driver,
int (*bind) (struct usb_composite_dev *cdev));
ARGUMENTS¶
driverthe driver to register
bind
the callback used to allocate resources that
are shared across the whole device, such as string IDs, and add its
configurations using usb_add_config(). This may fail by returning a
negative errno value; it should return zero on successful
initialization.
CONTEXT¶
single threaded during gadget setupDESCRIPTION¶
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.AUTHOR¶
