How to build a USB device?

I want to build/program a USB HID device (yes, a human interface device device).

So I'm wondering if anyone out there has programmed their own USB devices, and might have some tools/platforms they can recommend?

I've started using LPCXpresso, because I had a dev board on my desk.

But it's not super intuitive, it's a bit unreliable (the program/debug interface, that is, the target chip is fine), and the example I've used as a foundation has some interesting limitations / design decisions. LPC also doesn't seem to have a hugely useful online following, at least not for the phrases I've been Googling.

I'm using Linux on my PC, so I've become familiar with the following tools, which have been of great help: dmesg, lsusb, evtest

Bonus side question: I've also got a comms-class interface, which shows up as /dev/ttyACM0, and works alright, except on connection the computer sends AT commands to it. Any ideas of what to change in the descriptor to make Linux think it's a virtual com port, rather than a modem?

Making USB devices – end to end guide to your first gadget

A very nice writeup and intro into USB, although - it's very focused on using an ST microcontroller, which is a lot more steps and toolchains compared the the recent ESP32 ecosystem that offers a number of easy plug-and-play ways to make USB devices work (for example, several projects from Adafruit's learning pages provide basic use cases). Another issue is differential pairs - having designed several working USB boards myself, this has not a concern for beginners, mainly relevant for doing high-speed work. USB controller ICs (as used typically with arduio/esp) can handle a lot of the details for you, so doing the calculations seems overkill, especially for someone making their first gadget.

Hacker's Field Guide: Arduino Foundations: Basic electronics and software for success with Arduino projects

How can I tell the difference between a temperature sensor and a transistor? When do I use a for loop versus an if statement? You're starting (or want to start) working with Arduinos but are overwhelmed with everything related to both the electronics and programming. Harley Pebley is a life-long maker who has been there. He knows first hand the overwhelming feelings of not knowing where to start and wants to guide you step by step through your first steps. This introductory guide teaches you: * The basic electronics components that come with most Arduino starter kits. * What a program is, how it's structured and the building blocks to make one. * How to setup your computer to start working with Arduinos. * And the various models of Arduino that are available to choose from. You'll learn the fundamentals of the Arduino and feel more prepared to jump into your first projects.

How does USB device discovery work?

What happens when you first plug a USB device in? There's a whole bunch of negotiation where the computer discovers what a USB device is capable of. In this video I capture the conversation and walk through what's going on.

Jan Axelson's Lakeview Research

This book is for developers who are involved with designing or programming devices that use the Universal Serial Bus (USB) interface. If you are a hardware designer, if you write firmware that resides inside USB devices, or if you write applications that communicate with devices, this book is for you.

The USB interface is versatile enough to serve just about any device function. Familiar USB peripherals include mice, keyboards, drives, printers, speakers, and cameras. USB is also suitable for data-acquisition units, control systems, and other devices with specialized functions, including one-of-a-kind designs. The right choices of device hardware, software drivers and development tools and techniques can help you design devices that perform their functions without errors or user aggravation. This book will guide you along the way.
