I installed a PCI USB 3.0 card and now one out of four cpu's keeps up running nusb3mon.exe. Meaning that I have a CPU load of 25% all the time. Did anyone have the same problem before?

Had no problems with the onboard USB 3.0 ports of my Asus M4A89GDT. Operating system Window7 64bit

Driver update seem to solve the problem. Should have tried that first :-( Therefore, if anyone has the same problem the drivers from the CD, which came along with the card, are not working correctly. I will update if problem occurs again.
