# usb\_autopm\_set\_interface(9)

set a USB interface's autosuspend state

## NAME

usb\_autopm\_set\_interface - set a USB interface's autosuspend state

## SYNOPSIS

**int usb\_autopm\_set\_interface(struct usb\_interface \*** *intf***);**

## ARGUMENTS

*intf*

the usb\_interface whose state should be set

## DESCRIPTION

This routine sets the autosuspend state of *intf*'s device according to *intf*'s usage counter, which the caller must have set previously. If the counter is \<= 0, the device is autosuspended (if it isn't already suspended and if nothing else prevents the autosuspend). If the counter is \> 0, the device is autoresumed (if it isn't already awake).
