Description
USBDevInfo (USB Descriptor Explorer) is an utility for inspecting USB devices with clear, structured details—built for debugging, validation, and reverse-engineering.
Connect a device and view:
- Vendor/Product IDs (VID/PID) with resolved names (when available)
- USB version, speed, class/subclass/protocol
- Configurations, interfaces, and endpoint breakdowns
- Power hints (max power)
- Input peripherals (keyboard/mouse) via Android InputManager
With per-device permission granted, USBDevInfo can also retrieve advanced data such as:
- String descriptors (manufacturer, product, serial, interface strings)
- Descriptor tree parsed from raw descriptors
- Device state (GET_STATUS / GET_CONFIGURATION / GET_INTERFACE where supported)
- HID report descriptors and a readable summary
Designed to be fast, privacy-friendly, and practical for daily troubleshooting.
