Will USB3-HUB7-81X (old I know) run @ 3.0 USB speeds when connected to Macbook USB C port?

Hi…I’ve got an older USB3-HUB7-81X and I have it connected to a 2019 Macbook Pro USB C port using a Syntech USB C to USB Adapter. When I run Apple’s System Information tool, it shows all my USB 3 devices (external HDs) are USB 2 devices running at 480 mbs. Is this expected?



Thanks for asking!

Yes it should connect at 3.0 speeds. Are you sure that the devices are connecting at 2.0 speeds? macOS should show 1.1/2.0 devices under a 2.0 tree and USB 3.0 devices under a 3.0 tree. It varies slightly depending what macOS version you have of course.

Here is my system with a hub attached. The hub itself shows up four times (twice for 2.0, twice for 3.0). Currently I have no 3.0 devices attached so everything shows up as 2.0:

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
