The issue is that USB ports work only starting the kernel with "pci=noacpi" parameter. Without it, nothing plugged into usb ports is detected. In particular, "lsusb" returns "unable to initialize libusb: -99". The same happens with a 3.13.11 kernel (same config). I've tried newer kernels (3.18.8, 3.19) and they show the same issue. With the difference that, with "pci=noacpi" they don't start at all.
