💖 Device::USB::DevEndpoint 💖

okay bestie, gather round, because we're about to talk about a little Perl module from the 3pm section — User Contributed Perl Documentation, if you wanna be fancy about it. Device::USB::DevEndpoint is out here encapsulating a USB Device endpoint and all the methods that lil object would support. she's giving ✨ access ✨, she's giving 🎀 libusb wrappers 🎀, and honestly? iconic.

🌸 NAME 🌸

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

✨ VERSION ✨

Version 0.38 🦋

🫶 SYNOPSIS 🫶

so Device::USB:DevEndpoint provides a Perl object for accessing an endpoint of an interface of a USB device using the libusb library. literally that's the whole vibe. here's the code, copy it character for character bestie:

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";

and if you wanna know what all those endpoint attributes actually mean? go read the USB specification, bestie. not me explaining it. the spec ate and left no crumbs. 📚

💜 DESCRIPTION 💜

This module defines a Perl object that represents the data associated with a USB interface endpoint. and the whole point? the object gives you read-only access to the important data associated with the endpoint. no writing, no touching, just looking respectfully 🫶. main character is the data.

🎀 METHODS 🎀

There are several accessor methods that return data from the interface. each one is named after the field that it returns, which is honestly so considerate of them. the accessors include:

  • bEndpointAddress
  • bmAttributes
  • wMaxPacketSize
  • bInterval
  • bRefresh
  • bSynchAddress

slay. six little accessors, all doing their thing, no notes. ✨

💀 DIAGNOSTICS 💀

This is an explanation of the diagnostic and error messages this module can generate. (yes bestie, that's really all it says here. the manpage is being mysterious. lowkey mysterious. 🙈)

🧚 DEPENDENCIES 🧚

This module depends on the Carp, Inline and Inline::C modules, as well as the strict and warnings pragmas. and obviously, libusb must be available — because that is, fr fr, the entire reason for the module's existence. no libusb, no module. periodt. 💅
