tinyusb-integration

tinyusb-integration is a skill for Claude Code, Codex from easyzoom/aix-skills. It costs 42 tokens per session (736 once invoked), scanned A, original, MIT.

An integration guide for TinyUSB, a USB software stack for microcontrollers. It covers USB device and host modes, descriptors, controllers, interrupts, and classes such as serial, storage, keyboard, MIDI, and vendor devices.

In plain words
What is it for?
Use it to add or debug USB on a microcontroller, including CDC serial, mass storage, HID, MIDI, composite devices, and custom USB classes.
Why use it?
It helps diagnose devices that fail to appear on a computer, reset repeatedly, expose the wrong identity, or transfer data incorrectly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tinyusb-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

TinyUSB Integration

Overview

Use this skill to integrate TinyUSB by separating board support, USB controller driver, descriptors, class drivers, interrupts, clocks, and endpoint buffers. USB bugs are often descriptor or controller-state problems before application logic.

When To Use

Use this skill when:

  • The user wants to add or debug TinyUSB on an MCU.
  • The issue involves USB enumeration, CDC serial, MSC, HID, MIDI, vendor class, device/host mode, descriptors, endpoints, DCD/HCD, or TinyUSB tasks.
  • The target needs a new MCU/board port or custom USB class configuration.

Do not use this skill when board power, USB D+/D- wiring, or clock source is unverified. Use hardware-interface-debug first.

First Questions

Ask for:

  • MCU/board, USB controller, device/host mode, and TinyUSB version.
  • USB class: CDC, MSC, HID, MIDI, vendor, composite, or host stack.
  • RTOS/bare-metal runtime and where tud_task/host task runs.
  • USB clock source, VBUS detect, pull-up control, and interrupt routing.
  • Descriptors and tusb_config.h.
  • Host OS symptoms: no enumeration, code 10, repeated reset, missing COM port, wrong VID/PID, or transfer failure.

Integration Checklist

  1. Prove hardware prerequisites. USB clock, D+/D- wiring, VBUS, pull-up, ESD/protection, and connector orientation must be correct.

  2. Configure tusb_config.h. Enable only needed roles/classes and set endpoint buffer sizes within RAM limits.

  3. Verify descriptors. Device, configuration, interface, endpoint, string, VID/PID, class/subclass/protocol, and composite descriptors must agree.

  4. Run TinyUSB task regularly. In bare metal or RTOS, ensure device/host task and interrupt handling are scheduled correctly.

  5. Check class-specific behavior. CDC needs line coding/control; MSC needs safe block device hooks; HID needs report descriptors and polling interval.

  6. Capture host evidence. Use OS device manager, lsusb, USB logs, or protocol analyzer when enumeration fails.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tinyusb-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 736 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
