NAME

USB::Descriptor::Interface - USB Interface Descriptor

VERSION

Version 1

SYNOPSIS

An object representation of a USB interface descriptor.

use USB::Descriptor::Interface;

my $interface = USB::Descriptor::Interface->new( description => 'My First Interface' );
$interface->class(0);
$interface->subclass(0);
$interface->endpoints( [ USB::Descriptor::Endpoint->new() ] );
...

DESCRIPTION

USB::Descriptor::Interface represents a USB interface descriptor. When added to the descriptor tree of a USB::Descriptor::Device object it can be used to generate the data structures needed to compile the firmware for a USB device.

CONSTRUCTOR

$interface = USB::Descriptor::Interface->new(description=>$description, ...);

Constructs and returns a new USB::Descriptor::Interface object using the passed options. Each option key is the name of an accessor method.

ARRAYIFICATION

$interface->bytes (or @{$interface} )

Returns an array of bytes containing all of the fields in the interface descriptor as well as all of the child endpoint descriptors.

ATTRIBUTES

$interface->alternate

Get/Set the alternate setting value (bAlternateSetting).

$interface->class

Get/Set the interface class (bInterfaceClass).

$interface->class_descriptor

Get/Set the interface class descriptor object reference.

$interface->description

Get/Set the interface's description string. A string descriptor index (iInterface) will be automatically assigned when arrayified by USB::Descriptor::Configuration.

$interface->endpoints

Get/Set the array of USB::Descriptor::Endpoint objects. All of the endpoints in the passed array will be arrayified when the interface object is arrayified by USB::Descriptor::Configuration.

$interface->number

Get/Set the interface's number (bInterfaceNumber).

$interface->protocol

Get/Set the interface's protocol (bInterfaceProtocol).

$interface->subclass

Get/Set the interface's SubClass (bInterfaceSubClass).
