I understand that after you updated the BIOS to version 100 you now have 2 unrecognized USB devices.
In regards to the problem that you are experiencing, I recommend you to first try uninstalling them in Device Manager, install the latest chipset driver and the Intel(R) USB 3.0 driver.
If problem continues, make sure that the devices connected to the motherboard are not causing this, you can remove all of the USB devices including keyboard and mouse when you have the Device Manager window open, it should refresh automatically.
Thanks, uninstalling and reinstalling the USB3 driver fixed it! I already had the latest chipset driver installed.
