USB Descriptor Explorer

Inspect USB devices with full descriptor and HID details
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.
