Thmyl Brnamj USBUtil v2.2 – A Comprehensive Overview 1. Introduction Thmyl Brnamj USBUtil v2.2 (hereafter USBUtil 2.2 ) is a lightweight, cross‑platform utility library that abstracts low‑level USB communication into a clean, object‑oriented API. Designed for embedded engineers, device‑firmware developers, and desktop‑application programmers, USBUtil simplifies tasks such as device enumeration, control‑transfer handling, bulk/interrupt data streaming, and hot‑plug event management. # Register callbacks usbutil
# Register callbacks usbutil.register_arrival_callback(device_arrived) usbutil.register_removal_callback(device_left)
# Build cmake --build . --config Release
