USB problem need help please

[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 on how to solve it

have a look here to see if you can reinstall the drivers

 

[multisync666]

have already tried this way but no luck and tried to update drivers

 

[edklite]

did you try puting in your xp cd and having the driver wizard search that for dirvers instead?

Just delete the 7 and reboot.

If they come back, it may have something to do with the 2.0 USB not being installed.
