Comment 25 for bug 1437492

Another finding I'd like to share that temporarily "solves" this problem.

The Asus Z87 Maximus VI Formula board I have allows me to enable/disable USB controllers from the BIOS. I disabled the Asmedia USB3 controller and all the issues seem to go away:

1. laggy BIOS initialization
2. slow udev initialization
3. and USB devices not being available until after about 40-50 seconds after boot

Since the controller winds up "dead" on reboots or power cycles without power cut, any device I connect to those USB ports don't work anyway. There is no point for me to use them for any devices.
