USP major Problem root hub

[multisync666]

I have built my pc i thought everything was fine but on checking in device manager i have found a problem with the usb root hub.
There are 7 entries for the intel family universal host controller that have no problems.
Below that there are 7 entries for usb root hub these have yellow exclamation marks and on checking properties it sayes driver may be corrupted or missing code 39.
Never ever having come across this problem before would appreciate some advice please
