About this app

USB Information is a professional USB device inspection and testing tool designed for Android. When you connect a device via USB Type-C, this app automatically detects it and displays detailed information, including the device name, manufacturer, Vendor ID (VID), Product ID (PID), and more — no root required.

🔍 Key Features
✅ Home Page — Real-Time USB Device Detection
Automatically scans for connected USB devices

Lists multiple devices with:

Manufacturer name

Product name

VID & PID

Fully supports USB Type-C OTG devices for phones and tablets

🧩 Page 2 — Interface Overview
Each USB device may expose multiple interfaces

Tap a device to view:

Interface ID

Class / SubClass / Protocol

Number of endpoints

System path (e.g., /dev/bus/usb/...)

🧪 Page 3 — USB SET REPORT / GET REPORT Tool
After selecting an interface, enter testing mode

Manually configure:

Endpoint (EP)

Report Type

Report ID

Use 64-byte (8x8 grid) hex input to define payloads

One-tap commands:

SET REPORT: Send data to the device

GET REPORT: Read response from the device

Supports standard HID device testing such as mice, keyboards, controllers, and microcontroller-based modules

💡 Who Is It For?
