Hello Abaker,
The USB drivers we link in the FAQ are specifically for the various Intel CPUs that support USB 3.0. If you are using an external card, then those drivers won’t be applicable. We recommend a class of Intel CPUs (4th generation or later i5/i7’s) because they implement USB 3.0 support in hardware that has proven to work at the sustained throughput we need (Typically referred to as native USB 3.0 support). We have a poor track record with external cards and third party USB 3.0 vendors such as Renesas and ASMedia.
Since the card has worked for you in the past, it might be that you need to find the latest drivers for the card. Or it might be the card isn’t going to work in combination with this PC. The Xeon processor you linked was made before the Native USB 3.0 push from Intel and widespread USB 3.0 adoption on PC hardware.
Regardless, both the CPU and the external card are outside the minimum recommended PC requirements, and I suspect this is why you are seeing the “Device Not Found” error message.
Let me know if you have additional questions.
Regards,
Andrew
