Device::USB::DevEndpoint

This class encapsulates a USB Device endpoint and the methods that object would support.

NAME

Device::USB::DevEndpoint - Access a device endpoint returned by libusb.

VERSION

Version 0.11

SYNOPSIS

Device::USB:DevEndpoint provides a Perl object for accessing an endpoint of an interface of a USB device using the libusb library.

    use Device::USB;

    my $usb = Device::USB->new();
    my $dev = $usb->find_device( $VENDOR, $PRODUCT );

    printf "Device: %04X:%04X\n", $dev->idVendor(), $dev->idProduct();
    $dev->open();

    my $cfg = $dev->config()->[0];
    my $inter = $cfg->interfaces()->[0]->[0];
    my $ep = $inter->endpoints()->[0];
    print "Endpoint:", $inter->bEndpointAddress(),
       " name: ", $dev->get_string_simple($iter->iInterface()), "\n";

See USB specification for an explanation of the attributes of an endpoint.

DESCRIPTION

This module defines a Perl object that represents the data associated with a USB interface endpoint. The object provides read-only access to the important data associated with the endpoint.

METHODS

There are several accessor methods that return data from the interface. Each is named after the field that they return. These accessors include:

bEndpointAddress

bmAttributes

wMaxPacketSize

bInterval

bRefresh

bSynchAddress

DIAGNOSTICS

This is an explanation of the diagnostic and error messages this module can generate.

DEPENDENCIES

This module depends on the Carp, Inline and Inline::C modules, as well as the strict and warnings pragmas. Obviously, libusb must be available since that is the entire reason for the module's existence.
