Hi:

 

You need this driver for the base system device...

 

The JMicron Media Card Reader Driver enables the integrated media card slot in supported notebook models that are running a supported operating system.

There can be several devices that can be labeled Unknown when the driver is missing.

 

This is the most common unknown device driver for your model.

 

This package provides the HP 3D DriveGuard Software for supported notebook models that are running a supported operating system. HP 3D DriveGuard Software protects the hard drive by parking the heads if the notebook is accidentally dropped, or is abruptly impacted by another object.

If the above is not the right driver, then please post the hardware ID for the unknown device, and then I will post the link to the driver you need.

 

Use this guide to find the hardware ID...
