Device::USB::DevEndpoiUser)Contributed Perl DocumenDevice::USB::DevEndpoint(3)

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.
