initializing issues for USB3 hub

I have recently bought a USB3 hub(super speed 7 port usb3 hub, model USB3-HUB7-81x). It is attached to a USB3 port on my computer, with no devices connected through it).
On 2 separate USB2 ports, I have a keyboard & mouse. At boot, while the hub is connected, I get a “no keyboard detected” message, for a few seconds. After this, the PC boots up normally.
If at boot time i disconnect the hub(unplug the data cable), the system boots up without any error messages.
As far as I can tell, the USB2 ports do not get initiallized in a timely manner(or, USB3 ports have priority of some sort).
Any ideas what I could do?
I have already contacted the MB manufacturer(ASUS) but their suggestions failed(BIOS reset and changing the USB3 slot). I have no idea why this would be and any help would be appreciated.

Hi Blue,

Thanks for contacting Plugable support, and sorry to hear about the issues encountered while setting up our device- we’ll be happy to help!

Could you please run our support tool, PlugDebug, and send back the .zip file it creates on your desktop?

Knowing things like what OS and USB 3.0 hardware your system uses is crucial to being able to help.

Please be sure to have the device attached directly to a USB port on your computer while running the tool as this helps us to collect relevant errors about the device when the tool is run. Being able to review complete system details in a standard format helps us to more quickly recommend the right steps.
