Micro SD card reader not working: SD Storage Class Controller - Driver not working Switch 12S

Super8j

I have an Acer Aspire Switch 12S running Windows 10 which is totally up to date. It has a slot for a Micro SD Card. When I put a Micro SD Card into the slot, the laptop makes a sound as if mounting a new drive. However, when looking in Explorer, the drive is not visible. Looking at the Device Manager, there is a yellow warning against "SD Storage Class Controller". I have run the update driver utility on that entry: it says the most up to date driver is installed. I have run the troubleshoot utility but no problems are found. As a check, I have used a USB adapter to mount the Micro SD Card through one of the USB slots and it works absolutely fine, so the SD Card is not at fault. I have trawled the internet and tried a few resets etc but nothing is fixing the problem with the SD Storage Class Controller. Is there anyone who knows of a fix for this issue please. Thank you in anticipation,

Go to your specific acer model, look at the realtek card driver.

If it looks like a realtek usb based sd card driver, then download this:

If it is a realtek pci based sd card driver, then download this:
