• Allows customization of USB descriptors (VID/PID, strings), GPIO/LED behavior, and product policies (timeouts, spin-up/down, sleep)
• Offers example configurations and reference board support to accelerate integration

What’s typically included:

• Full firmware source and headers
• Project files and build scripts
• Example configurations and prebuilt images
• Release notes and documentation
