Instantly See How Your USB Devices Are Really Performing
Ever bought a fast new drive, only to wonder why it’s transferring files like it’s 2006?
That happened to me—and the culprit was a USB-C cable that looked fine, but was only negotiating USB 2.0 speeds. Same shape, drastically slower performance.
I built USB Connection Information to save myself from this frustration—and now it can save you too.
What It Does
USB Connection Information is a lightweight, privacy-respecting Mac menu bar app that gives you real-time details about your USB devices:
USB Version & Speed Instantly see if your connection is using USB 2.0, 3.0, 3.1 Gen 2, or higher—and at what negotiated speed.
Device Details View manufacturer name, vendor ID, product ID, and serial number.
Power Information Check the current power draw and the maximum wattage supported by the port.
Plug & Go Just plug in a USB device and glance at the menu bar—no more digging through System Information.
