When I plug in my device which is USB 2.0 into a 3.0 slot (cause that is all I have) [495042.943074] usb 5-2: new low-speed USB device number 6 using xhci_hcd [495043.100076] usb 5-2: device descriptor read/64, error -71

I receive the above error.

Is there a flag or setting that tells the USB to in a 2.0 mode ?

You should be able to use USB2 devices in a USB3 port with no issues, as others have said, they use different pins and both are there.

I have never seen anyone have to do anything to use USB2 devices on a USB3 port except plug it in.
