USB Hub – How to Check if It Supports USB 3.0

macbook prousb

I recently bought a USB type-C hub for my MacBook Pro. I found the data transfer speeds to be quite low (from my USB 3.0 external hard disk). I suspect that the USB hub doesn't support USB 3.0 data transfer speeds. How can I confirm this?

Best Answer

  1. Open System Information app before you plug in your hub.
  2. Navigate to "USB" in the list and click.
  3. Note which information isn’t about the device you’re about to test.
  4. Then plug in the hub and refresh the window contents.

Here is an example of mine. You can see it is identified as USB 3.0 capable, speed up to 5Gb/sec:
