Hello all,
Last week, I purshased the maximus IV extreme and I'm happy of everything except the usb 3.0 ports.
Sometimes when I power up my system my usb devices (mouse and keyboard) seem to be disabled. I think it comes from the NEC usb controller. When the system boots the bios alerts me about the non presence of any keyboard. I tried to update my bios at 1409 version, it doesn't solve the problem. If I connect my devices in another usb 3.0 ports, it seems to work but after a while those ports become also dead and at this point 4 usb ports are useless.
The only solution I found is to completly shutdown the computer (by switching off the power supply). After that all seems to work normally, all ports become available again for a moment...
I try to update the nec controller firmware but the updater doesn't work with multiple usb controller.
Any of you have an idea how to solve the problem ?
