Only 15 usb ports even with xhciportlimits = true

[Yomiro]

Actually an HS** USB2 port personality, if it is on a physical USB3 port - i.e it has more than 4x pins and usually blue or red inside - should be set to UsbConnector type - "3" not "0".

It is correct that you can enable or disable whichever logical port you need to get to down to the 15-limit, however you should not specify a physical port - UsbConnector type - to be anything other than it physically is.

Hope that helps.

Thanks for the explanation.
