Unable to find Drivers for USB3.0 PCIe card

[Monokeros]

This card is currently detected in my BIOS but I'm unable to find the drivers for it. I sent an email to the manufacturers but when I try and run the installation file it says it can't detect the hardware on my system.

Did you check in Device Manager to see if there is a yellow ! , if not, the driver is installed

Those hardware ID's are for an Intel, 8086 is Intel's Vendor ID,

PCI Vendor and Device Lists

The closest match is a PCI simple communications controller,

Says right here there`s a driver cd in the package.

Someone did a switch on you. As derekimo pointed out that's an intel (not a VIA) chip. Your hardware IDs are for an Intel USB 3.0 controller. Try the Intel driver update tool (or send it back if it;s a problem as it's not what you think you ordered)

It says USB controller on those ID's.

@derikmo
Every Plug and Play device has its hardware IDs (as well as Compatible IDs) burned into device firmware by the vendor. The IDs are sent to Windows as part of PnP protocol. Windows searches for drivers that match any of the Hardware or Compatible IDs it receives from the device. (And as you already noted, in this case the IDs reveal the device is an Intel chip)

We're seeing the h/w IDs of the plug and device so are be independent where it connects to the PCI bus.

OK, I was aware of the hardware ID's, why is it listed as a USB controller?

I'll qualify all this with "is my best understanding" of how this stuff works (based on readings and trying to look at Windows "under the hood".)

The vendor also burns a descriptive "name string" into Plug and Play device firmware. From observation, this string is typically a very generic sounding name for the device. (This name string is just a comment to help us humans as far as Windows is concerned. It's in no way used to help find the driver)

From what I've observed:
> Windows displays the name string it found in device firmware when it can't find the device driver
> But once a driver is found, Windows displays the device name defined within the driver

So, in this case, we're seeing the name USB Controller as that's the name string Intel burned into the chip firmware. And no driver found so that's the name displayed

Another common example: When a driver's not found for a Hi Def Audio device, its usually displayed as an HD Audio device on HD Audio Controller (that's the generic name burned into the firmware). But once the driver is found we see a vendor device specific name appear (such as Soundmax HD Audio)

Hope that helps!
