After I installed the card reader drivers (CardRdr_Jmicron_v1.00.16.1.zip), the icons in explorer for any of the card slots would be corrupted, and only show a default icon.
It seems like the icon file was not copied to the correct location.
To correct this, copy "JmCrIcon.dll" from the extracted driver archive, located in "CardRdr_Jmicron_v.1.00.16.01\CardRdr_Jmicron_v.1.00.16.01\Application\res\x32" to "%Windows/System32".
No reboot was necessary in my case.
