Went online to buy a USB hub so I could add a few more ports. But here is the warning I get: 2.4Ghz wireless devices, such as wireless keyboard and mouse adapters, may not work in close proximity to USB 3.0 devices or hubs. Connecting to a USB 2.0 port is recommended. Does this mean with a 3.0 hub my keyboard and mouse will not work? If so, what do you recommend I buy?
