I'm unable to use 8 of the 10 USB devices I have on a motherboard. Two USB 3.0 ports work, and all of the devices, if plugged into a hub, can be recognized and used if plugged through those 2 ports. However, the other ports are completely unresponsive. Thoughts/Ideas? The broken drivers are ehci-pci. xhci-hcd works on the usb 3.0 ports, but for 2 other usb 3.0 ports it does not work. The machine is being netbooted and running kernel 3.19-49-lowlatency (i've tried with generic as well). This same identical setup running off of a hard disk boot does not have this problem for any USB ports. Im lead to believe there may be a bug in the ehci-pci driver while using netboot. Thank you.
