Overview
This page contains a list of all known motherboards which do and do not work correctly with USB 3.0 using the NEC USB 3.0 PCIe host controller card.
 | A known issue with the NEC controller is that it passes the PCIe spread spectrum to the device through the USB 3.0 interface. The NEC controller does not have it's own reference clock for USB 3.0. If the motherboard has an out-of-spec PCIe reference clock (either incorrect frequency or excessive spread spectrum), the device attached to the USB 3.0 controller will not be able to track the signal and will fail to enumerate on the system. |
Compatible Motherboards/Cards
These USB 3.0 capable motherboards/cards are known to work with the My Book 3.0 with the built-in USB 3.0 controller using default settings/drivers
