Hi, I recently bought a wireless Corsair Void headset, which uses a USB for wireless connection, my problem is, which USB port do I use? The manual said it needed a 2.0 USB port to charge the headset, but I only have two 2.0 USB ports which my mouse and keyboard uses, and then there is a whole bunch of 3.0 USB ports left over, but I thought those were for storing something? So which USB port should I put my head set USB and charge port cable?
