USB Connection Information

That "10Gbps" cable might be running at USB 2.0 speeds. Your expensive dock could be throttled. USB Connection Information lives in your menu bar and shows the real performance of every connection...instantly.

STOP GUESSING. START KNOWING.

See actual negotiated speeds (not just specs), live charger wattage, device power draw, and which drives belong to which devices. Perfect for anyone who's ever wondered "is this thing working right?"
