The K9N SLI Platinum already worked for a year or so. Suddenly, USB doesn't work any more, or to be more precise it sometimes (very unfrequent) works for a few seconds. The controller is recognized by Windows XP and different Linux Distros. However, when, for example, I connect an optical mouse, it doesn't light up, and nothing happens. No entries in /var/log/messages or dmesg.
So, since it doesn't work under different operating systems, I thought this had to be a hardware error. However the other functions of the MB still worked, so I decided to buy a PCI USB Card with 4 Ports. It also doesn't work, although the controller is recognized! The really strange thing is that it works in the rare cases when the onboard USB ports do work for a few seconds. I also tried to disable the onboard controller, but that didn't change anything.
What I really cannot understand is what kind of error can cause all connected USB controllers on a mainboard to malfunction!
Thanks in advance!
