This class encapsulates a USB Device endpoint and the methods that object would support.
Device::USB::DevEndpoint - Access a device endpoint returned by libusb.
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()->; my $inter = $cfg->interfaces()->->; my $ep = $inter->endpoints()->; print "Endpoint:", $inter->bEndpointAddress(), " name: ", $dev->get_string_simple($iter->iInterface()), "\n";
See USB specification for an explanation of the attributes of an endpoint.
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.
There are several accessor methods that return data from the interface. Each is named after the field that they return. These accessors include:
This is an explanation of the diagnostic and error messages this module can generate.
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.

Thanks go to various members of the Houston Perl Mongers group for input on the module. But thanks mostly go to Paul Archer who proposed the project and helped with the development.
