PCI Express Root Complex

Question

PCI Express Root Complex (Express Card 34mm USB 3.0, 2 Port) Hi, I am running: DELL Latitude E6320 WINDOWS 10 PRO (Version 1709) (OS Build 16299.192) I purchased a PCI Express Card on eBay and the driver disc does not work, therefore I have no driver to install for the 'Unknown Device', and very little knowledge on how to troubleshoot this issue. My Dell laptop recognises the driver in the Express Card Slot, I have tried Googling the numbers on the card (shown in the image), used the troubleshoot feature of Windows attempting to seek for the driver, have tried installing a few updates and drivers (Windows, and recommended DELL via detection feature)...Nothing I tried provided a solution. I am not very good at computer troubleshooting,  I have seen other posts of people experiencing the same issue as myself, posted under older versions of Windows section, and those posts have been successfully resolved. I'm hoping my issue is going to be easy to resolve too.  Print Screen- of my Device Manager: https://goo.gl/7Dyxpe Photo- Express Card I need driver for: https://goo.gl/9MvB6o  If anyone is aware of this issue and is able to assist with a solution, please kindly help me get this to work.  Your help is very much appreciated. Thank you in advance, -Leah

The first Picture ACPI\SMO8800\1 is not a USB3 card its the ST Micro Electronics Free Fall Sensor.

The Express Card USB3 has NEC RENESAS uPD720202 clearly marked which means this has NATIVE WINDOWS 10 drivers. Any Driver Disk would be for Windows 7 or 8.0 but not 8.1.

ST Micro Electronics Sudden Motion Sensor

The USB3 XHCI express card in your picture says NEC UPD 720202 chipset which is natively supported by Windows 10.

You don't say what OS you have but the E6320 is 'old hardware' and I would suspect USB 3.0 is not supported.  There was no USB 3.0 when this unit was developed.
