Now that is alot of useful information! Much appreciated!! Currently my SD card slot is empty, my flash drive plugged into USB-1 via supplied cable and a cable for my phone hooked to USB-2. However, I usually just use a Bluetooth connection for my phone. Side note, my phone is the Motorola Droid Turbo running Kitkat, because they have not yet updated it to lollipop, which, I guess limits the apps and thing that one can do in my situation. Is there any advantage to plugging my phone in rather than just using the bluetooth connection?
