    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?
