USB Descriptor Explorer

USB Descriptor Explorer (USBDevInfo) is a utility for inspecting USB devices on Android with clean, structured output. It is built for debugging, validation, and reverse-engineering.

Plug in any USB device (OTG / host mode) and instantly explore:

* Vendor ID / Product ID (VID/PID) with resolved names when available

* USB version, speed, and device class/subclass/protocol

* Full configuration, interface, and endpoint breakdown

* Power hints (Max Power)

* Input peripherals (keyboard/mouse) detection via Android InputManager

### Advanced inspection (with per-device permission)

After you grant USB permission for a connected device, USBDevInfo can also retrieve deeper data such as:

* String descriptors (manufacturer, product, serial, interface strings)

* Parsed descriptor tree from raw descriptors

* Device state queries (GET_STATUS / GET_CONFIGURATION / GET_INTERFACE when supported)

* HID report descriptors with a readable summary

### Perfect for USB Diagnostics

USBDevInfo helps you quickly validate what a device *really reports* to the host, making it ideal for:

* USB debugging and compatibility checks

* Hardware validation and QA

* Descriptor analysis for labs and security research

* Verifying endpoints, power requirements, and HID behavior
