If any of the issues on your log are related to BTHUSB and Bthenum, chances are that the new Bluetooth config from the Windows 10 update is somehow causing conflict with the USB detection system, like it happened to me.
Solution: Find the last supported Bluetooth drivers for your PC or Laptop model (even if they are for Windows 8.1), download them and reinstall. After restarting, my USB detection worked like a charm.
I sincerely hope this was helpful to you.
NiTeNull,
I made an account just to thank you. My USB ports were acting really slow. Opened up the event logs and found that a certain program I had installed Mobizen (it allows you to display your phone's screen on your PC) was erroring/timing out each time I plugged in a USB device and that was halting everything up. Thanks for leading me to the solution. You sir, are amazing! Oh and by the way I am on Windows 7 for those of you that care (:
