Thanks, that would be the preferred port so we can let that be.

I'll have a look for a driver for you.

You're welcome.

Those numbers show up as a USB3 controller,

Which doesn't sound right because that computer was originally a Vista computer.

And your motherboard specs don't mention any USB3 ports.

I'll keep looking to see if I can find something, I think a chipset driver is really what you need honestly.

Do your USB ports work?

Also can you expand the bottom USB host controller on your device manager shot and post that.

I had Installed a 3.0 USB expansion card some time ago (Don't remember the brand) it was a PCI card and just recently added a front 3.5" usb 3.0 to the front of the machine, (I/O crest USB 3.0 Internal Hub 4 Port). The later did not require drivers, I recently checked their site for drivers, but found none.

The first picture shows the usb3.0 expansion card.
The second shows the recently added front expansion card for drive bay (Attached to the first 3.0 Card).
The third picture shows the PCI location of the original expansion card.

Well, that clears up why they are being reported as USB3.

Yes, that is what I was wanting to see, Thanks.

I still think you need a chipset driver for those to get recognized.

Do your USB3 ports work?

Yes, both back and front ports seem to work fine.
I wondered about unplugging the front expansion bay, re-booting, then power down, plug in the front and re-boot and see If it loads a driver?

It's worth a try, it might just work.

The only driver I can get to download from this place,

PCI Vendor and Device Lists

For those hardware ID's is from Dell, the numbers match up but I'm reluctant to suggest it.

I will say I have done that on other computers before, but it was me doing it so I could undo it if needed.
