HID Descriptor Parser

Live Demo

Small toolset to parse and display USB HID (Human Interface Device) report descriptors in a readable form.

Features

• Parse HID report descriptor bytes (Main / Global / Local items)
• Decode Usage Pages, Collections and common usages
• Little-endian multi-byte handling (signed by default)
• Optional PDF extraction helpers to build usage tables

Local testing

• From project root run:

python -m http.server 8000

• Open http://localhost:8000/index.html and paste descriptor bytes, click "Parse".

Usage notes

• The parser expects hex bytes (space-separated). Multi-byte values are shown little-endian.
