USB 3.0 interference

How much of a problem is this? Need a new USB hub

In 2012, Intel published a white paper documenting the issue, why it happens, and mitigation options. It all boils down to the signal-to-noise ratio/RF noise generated by USB 3.0 devices. Due to the nature of the USB 3.0 specification, all data transmitted must be scrambled, and creates noise that can get as high as the 2.4 - 2.5 GHz frequency range. The noise can come from a USB 3.0 connector on the platform, the connector on an external peripheral device, or a USB 3.0 cable.

Should I find a usb 2.0 hub or just get a 3.0 hub?
