That's encouraging, but I'm afraid it's still possible that you could have problems again. When a device fails (inside your pedals), most often it will draw far too much current for a short amount of time (short), until it burns out, and then "opens" (like it's not connected anymore, and draws zero current). This could damage the source of the power (your motherboard). The port, or group of ports that the pedals were connected to before, could become unreliable, or eventually fail, causing you more heartburn. I always tell people "it's not going to heal itself"....if there's any problem, it's only going to get worse.
You should have a look at your motherboard manual that pertains to USB ports and controllers. Many times it will let you know which ports are on which controllers (USB0, USB1, USB2, USB3 on USB 2.0 VIA controller, etc.) There will be a diagram showing which ports are which. If you have a problem again, try disconnecting everything that is connected to the group of ports in question. For one thing, although you should be able to use your USB 3.0 ports for your USB 2.0 devices (game controllers), you certainly don't need to, since all game controllers are USB 2.0, and so you gain nothing by connecting them to USB 3.0. It will just work at USB 2.0 speeds. Game controllers just don't pass very much data, so it would be a waste to make them a USB 3.0 or 3.1 interface.
Hopefully you'll have enough other ports to connect to; if not, you can add an additional two USB 2.0 ports with an add-on card, or use a powered hub. You can stay in business.
I hope you won't have to deal with that situation, but if you do, you'll have some idea of what to try.
