NAME

USB::Descriptor::Configuration - USB Interface Descriptor

VERSION

Version 1

SYNOPSIS

An object representation of a USB configuration descriptor.

use USB::Descriptor::Configuration;

my $configuration = USB::Descriptor::Configuration->new( description => 'My First Configuration' );
$configuration->max_current(100);	# Max current in mA
$configuration->self_powered(1);	# Self-powered device
$configuration->interfaces( [ USB::Descriptor::Interface->new() ] );
...

DESCRIPTION

USB::Descriptor::Configuration represents a USB configuration 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

$configuration = USB::Descriptor::Configuration->new(description=>$description, ...);

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

Arrayification

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

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

ATTRIBUTES

$interface->description

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

$interface->interfaces

Get/Set the array of USB::Descriptor::Interface objects. All of the interfaces in the passed array will be arrayified when the configuration object is arrayified by USB::Descriptor::Device.

$interface->max_current

Get/Set the configuration's max current draw in milliamps (bMaxPower). Defaults to 0.

$interface->remote_wakeup

Get/Set the configuration's remote wakeup attribute (bmAttributes).

$interface->self_powered

Get/Set the configuration's self-powered attribute (bmAttributes).

$interface->value

Get/Set the configuration's configuration value (bConfigurationValue).
