Hi:
Please post the hardware ID for the unknown device.
To find the hardware ID, click on the unknown device in the device manager.
Then click on the Details tab at the top of the unknown device.
Now you will see a Property drop down list, and it will be set to Device Description.
Drop down on that list, and select the 2nd item (Hardware ID's).
Post the top string of characters that you see in the window.

Hi:
Yes, you are correct.
However, HP has the wrong driver listed for your notebook.
You need the JMicron card reader driver.
This is the one from the 4530s. Hopefully it will work for your model too.
The JMicron Media Card Reader Driver enables the integrated media card slot in supported notebook models that are running a supported operating system.
