|If you have enhanced USB showing in Device Manager then there are USB 2.0 ports currently installed. That is assuming they are working properly when you look at the properties of the device.|
Your board evidently has a mix of both USB types. Try a different port. Normally TWO USB ports are serviced by each USB controller. They will normally be located side by side.
Card readers can downgrade the speed of a USB 2.0 controller to 1.1 speeds. If you are using the port that is shared with a card reader that could explain the message.
Also, if using a high current draw non-external powered device I think that could cause the same issue.
How many USB ports do you have all together? Do you have a card reader?
