The USB card reader is attached to a PCIe USB 3.0 card which uses a standard Via Labs 805/806 chip as the ASMedia-Chip from my Asrock 970 Extreme4 does not work under Windows 10.
Nevertheless I got the driver, updated the firmware for the PCIe card, installed the driver (VL800 v4.70c) and rebooted the system. The problem persists.
