In addition to what Dan has asked, my experience with my Renesas USB 3.0 ports and USB3.0 external drives on my desktop computer is that each version update of Windows 10 substitutes generic Windows 10 drivers for my 2011 Renesas drivers, and reduces the speed down to USB 2 levels. I have to reinstall my old 2011 Renesas drivers to reacquire USB 3 speeds on my USB 3 ports.
So I would check the Device Manager, as Dan suggested, and see if you might have a "new" generic Microsoft driver for your SD card reader. If you can locate and download the appropriate driver, then you can inform Windows to update the driver, via the Device Manager, and tell it that you have a driver, and then browse to the correct driver that you downloaded and install it. It is important that you reboot to see if it works.
Just a thought, because it took me awhile, and assistance from Maingear (my computer manufacturer), to figure out why each Windows 10 version update was wreaking havoc with my Renesas USB 3.0 host/hub controller drivers. Hopefully Microsoft will fix this nuisance. In the meantime, I have the old 2011 Renesas drivers backed up to external media so that I can easily "recover" from the damage inflicted by future Windows 10 version updates.
I hope that this information might be helpful. Have a great day, and good luck.
