Is this your motherboard?

If so, you have 6 USB 2.0 ports, and 2 USB 3.0. The ports with blue are the
USB 3.0 ports. Therefore, your kernel needs EHCI (USB 2.0/1.0/1.1) and XHCI
(USB 3.0). (This is not including the internal connectors on your board which
might have a cable running to the front of your case as USB 2.0.)

No matter how special you think your setup is, you don't need OHCI. The EHCI
driver for the port is backwards compatible with a USB 1.{0,1} device. I've
tested this on my boards using the only USB 1.1 device I brought back from
China. If you doubt me, build your kernel with this:

CONFIG_USB_EHCI_HCD=y
CONFIG_USB_EHCI_PCI=y
CONFIG_USB_EHCI_HCD_PLATFORM=y

CONFIG_USB_XHCI_HCD=y

CONFIG_USB_OHCI_HCD is not set

CONFIG_USB_UHCI_HCD is not set

boot into it, issue "tail -f /var/log/messages" and plug in your USB devices.
