Windows 7: USB ports no longer working

The problem occurs with both wired and wireless mice, and all that I have are Logitech. I had a hub that I plugged into one of the USB ports, but everytime I plugged it in, the mouse (whichever one I was using) would stop working. I also have a USB external speaker--USB used for charging--and when I plug that into the second USB port, the mouse also stops working. So the problem seems to be the ports themselves, not the mice.

I did the battery drain, and for the time being, everything seems to be working, at least for the last 24 hours. I tossed the hub since it was a pain in the butt anyway, I have the speaker plugged in so it can charge, but it won't charge (brand-new), so I'm not sure if I have a problem with the speaker or whether the USB port isn't doing its job.

If you open Device Manager, then go to Universal Serial Devices and right click USB Root Hub. There should be a Power Tab. In there it will show you the current being drawn by devices. It sounds like your USB ports may have been damaged or are failing? I'm not sure how to confirm it one way or the other though?

There are 6 USB Root Hubs listed. Snips attached, but I'm not really sure what this is telling me. I have 2 places to plug in, so I assume those are the USB Composite Devices.

If you saw one with a high current draw, it would be an issue, and tell you what device was overloading the USB ports. I'm not sure why you have so many listings with only 2 ports to plug into. Laptops will use some USB ports internally for things like the keyboard and trackpad. That's still a lot though? I only have two USB Hubs listed on this desktop PC? It has 10 USB ports total. I'm running out of ideas and things to check.
