I have a few problems:
1. My one USB 3.0 does not recognize any device I plug in. In the device manager "Unknown Device" is displayed under "Universal Serial Bus Controllers" when something is plugged in. I can charge my phone in this port though. Actually, I just plugged in an older USB mouse I had and it worked briefly. I haven't had this happen with anything else. I know I had this mouse consistently plugged into this port when it was still working though. Hm... coincidence?
2. One of my two USB 2.0s works, but it will only recognize my newer USB Mouse, and nothing else. My last USB 2.0 will accept everything I plug into it; the older mouse, USB Keyboard, and Wacom Bamboo Pen and Touch.
3. I'm pretty sure this is unrelated, but Windows always fails to install update "Intel Corporation-Display-Intel® HD Graphics."
4. The device manager likes to refresh... a lot... and fairly irregularly.
I've tried re-installing and uninstalling the "Unknown Driver," but to no result.

I've dealt with the USB 3.0 for awhile now but it's only been recently that I've had problems with the USB 2.0s. I really need at least my two USB 2.0s to work though, so I can switch between my tablet and mouse. It would be wonderful though if all three would work.
