## Description

USB Host Test is a convenient Chrome extension designed to test your device's USB Host capability by detecting and listing attached USB devices. Simply run the app, connect your USB devices, and click find to see detailed information such as device serial number, vendor and product IDs, manufacturer and product descriptors, USB version, power consumption, and interface details.

This tool is especially useful for verifying USB hardware compatibility on devices running Android 3.1 or newer that support USB Host API.
