PCI Device has exclamation mark after installing W10P and SD Card reader not working

[ktburgh]

I bought an HP Envy used and installed Windows 10 Pro. On the Device Manager under "Other Devices" the PCI Device, PCI Simple Communications Controller and other device all have a yellow exclamation mark after them. Also, the SD card reader is not working. Are these two related? How can I fix them.

Thank you!

Hi:

What is the full model number or product number of your notebook?

Use this guide to find that information...

The PCI device is the Realtek SD card reader so that is why the SD card reader isn't working.

Hi Paul,

It's an HP ENVY TS 15 Notebook PC, Product number: E1P04AV.

Thanks.

You're very welcome.

You need this driver for the Realtek SD card reader:

You need this driver for the PCI Simple Communications Controller:

If you have any other devices that need drivers such as 'Unknown Device,' please post the hardware IDs for those devices so I can figure out what drivers they need.
