USB ports not working in OS X, works in Windows

Hi,

When I started up my iMac the USB ports stopped working. It didn't respond at all. The weird thing is that they work at the startup when you choose between Windows/Mac OS X when holding in ALT. They also work in Windows, but not in OS X. Does anyone know how to solve this problem?

Try performing the procedure as given in the following Apple KB articles:
