Test USB & OTG mouse buttons, scroll wheel, polling rate (Hz), and DPI accuracy.
Connect any physical USB or wireless dongle mouse to your Android device using a USB OTG adapter and run comprehensive diagnostic tests. Whether you are checking a new mouse, diagnosing double-click issues, measuring your sensor's polling rate (Hz), or testing scroll wheel accuracy, USB Mouse Tester gives you accurate, real-time hardware telemetry. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY TESTING MODULES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • BUTTON & CLICK TEST - Test Left, Right, Middle (Scroll Click), and Side Buttons (Back / Forward). - Real-time visual mouse diagram highlighting active button presses. - Double-Click Benchmark: Detect faulty switches, unintended double-clicks, and measure interval timing (ms). - Button Hold Stopwatch: Test switch contact stability and contact retention. • POLLING RATE (Hz) BENCHMARK - Measure real-time USB report updates in Hertz (Hz). - Benchmark at 1-second, 5-second, or 10-second capture intervals. - Live rate line chart displaying packet frequency fluctuations. - Detailed statistics: Average Hz, Peak Hz, and Min/Max interval timing in milliseconds. • SENSOR MOVEMENT & SPEED TEST - Interactive 2D canvas with customizable fading motion trails. - Real-time movement coordinates: instantaneous dX/dY and cumulative counts. - Speedometer: Measures tracking speed in counts per second (CPS) and peak speed. - Straight-line tracking deviation test to evaluate sensor jitter and smoothing. • SCROLL WHEEL TEST - Inspect vertical scroll step increments (+1 / -1). - Animated rotating dial showing scroll direction and velocity. - Individual Up/Down rotation counters and cumulative delta tracking. • DPI ESTIMATOR & SENSOR CALIBRATION - Calculate estimated sensor DPI (Dots Per Inch) across standardized physical distances (1 inch, 2 inches, 4 inches, 5 cm, or 10 cm). - Accurate count recorder with guided start and stop triggers. • GUIDED FULL MOUSE TEST WIZARD - Step-by-step 8-stage automated test sequence. - Verifies buttons, scroll wheel, tracking speed, and sensor stability in one workflow. - Generates a complete diagnostic report you can save, copy to clipboard, or share. • HARDWARE & USB DESCRIPTOR INSPECTION - View Vendor ID (VID) and Product ID (PID) in hexadecimal format. - Inspect USB Device Class, Subclass, Protocol, and Interface Descriptors. - Review endpoint packet sizes and transfer configurations. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ADDITIONAL FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✓ Test History: Review past benchmark scores and diagnostic reports anytime. ✓ Technical Event Monitor: View raw Android input events and motion timestamps. ✓ Dark & Light Themes: Clean, high-contrast interface designed for quick readability. ✓ Privacy Focused: No account registration required. Diagnostics run entirely on-device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HARDWARE REQUIREMENTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. An Android phone or tablet with USB Host (OTG) support. 2. A compatible USB OTG adapter (USB-C or Micro-USB to USB-A). 3. A wired USB mouse or a 2.4 GHz wireless mouse connected via its USB wireless receiver dongle.
