I use CF card and a card reader is only useful if it has a longer guide rail for the CF card, because this otherwise unrecognized and the pins are bent or damage the card. Almost all internal card reader have a completely unusable CF card management. This card reader is there a remarkable exception. The cards could be introduced cleanly and without canting. The card reader also has yet to USB3 ports. Connect the reader with a pin connector and a power connector (old power supply). I had to re install the USB3 driver at my board, then memory cards have been correctly recognized with high capacity. Inform non-intrusive StatusLEDs. I am excited about the part !!
