## Name

usb_driver_claim_interface — bind a driver to an interface

## Synopsis

`int usb_driver_claim_interface (` | struct usb_driver * driver,
| struct usb_interface * iface,
| void * priv`)`;

## Arguments

`driver`

  the driver to be bound

`iface`

  the interface to which it will be bound; must be in the usb device's active configuration

`priv`

  driver data associated with that interface

## Description

This is used by usb device drivers that need to claim more than one interface on a device when probing (audio and acm are current examples). No device driver should directly modify internal usb_interface or usb_device structure members.

Few drivers should need to use this routine, since the most natural way to bind to an interface is to return the private data from the driver's `probe` method.

Callers must own the device lock, so driver `probe` entries don't need extra locking, but other call contexts may need to explicitly claim that lock.

## Return

0 on success.
