When is usb3 not usb3?

I recently purchased from Amazon uk one of your Plugable® 7-Port USB 3.0 SuperSpeed Hub with 20W Power Adapter UK and EU Mains (VIA VL812 Rev B2 Chipset with Latest v9091 Firmware for Windows, M

Sold by: Plugable Technologies and connected it to my desktop. Unfortunately, whenever I connect one of my usb3 devices to it, I am told the device would perform better if connected to a usb3 port. Can you PLEASE tell me what I am doing wrong

Sorry about this issue.

I suspect your computer is running out of date USB 3.0 xHCI host controller drivers.

I’m going to contact you directly via email to get some diagnostic information from you.

Thanks,
