Another thing I have never seen (shows its been a few years for having a new computer !!)..on the back of the tower the USB 2 ports have the small circle/line symbol...like on a power switch. But not on the front ports. What's with that?
The trouble with markings on USB ports is that while there is a standard symbol set not all PC manufacturers stick to it. A USB 3 port should be blue and have a USB symbol and "SS".
If a PC USB port is capable of delivering enough current to charge a device or power stuff that needs the full USB specification current from the port it might have a lightning bolt symbol. Not always, because the USB spec means all ports should provide the specified current, so on a PC where they do provide the specified current there's usually no symbol saying they do. Some PC ports don't deliver the current the USB specification requires - e.g. some of the ports on the PC in my sig can't charge and run an iPad at the same time even though the USB spec says they should be able to, they only provide enough power to prevent the iPad battery discharging further while it's running, and enough to slowly charge when it's off.
The "on/off" switch symbol you describe, which I don't think I've ever seen, might or might not mean those ports aren't switched off if the PC is in sleep state, so can be used for peripherals like mice and keyboards that can be used to wake the PC up, or for charging devices. `Though stuff that's connected to charge usually gets plugged in at the front to the PC to make access to the necessary ports easier. Or maybe they mean something else.....
The motherboard manual might explain all this.
