Device manager is showing Enhanced USB? Got a screenshot?

Restart your machine and Press Del at the Bios Logo (as soon as your computer turns on)
Go to the Advanced tab by arrowing Right
Select USB Configuartion
Select USB 2.0 Controller Mode
Choose FullSpeed
Press F10 followed by return

If that doesn't fix it, do an sfc /scannow.

If that doesn't fix it, the USB 2.0 controller is likely toast. Buy a card if the mobo isn't returnable.

The data I found says 16x burn is about 21MB/s and Full Speed USB operates at about 12MB/s so it is possible you are actually burning at about 8x which is still pretty good.

I don't have a lot of knowledge in this area, nor interest really. Someone else may offer further edification.
