I am getting 'A timeout occurred while waiting for the EHCI host controller Asynchronous Schedule to transition to the enabled state. ' in event viewer. This happens when my wifi usb dongle is running at full speed usually. When this happens, all my usb ports power off or disconnect. This only seems to happen on AMD motherboards with windows 8. I just wanted to see if anybody knew a fix other than going with pci-e network card. Sorry if it all runs together, i'm at work lol.
