My Vorrezensenten is little to add. An indication perhaps, the device runs under XP without the supplied drivers. These bring the undermentioned drive icon feature. This is not described in the operating instructions very concise.
If the drivers are installed, then get the 4 new drives that generated the card reader, the work your own icons. This change, when a card is inserted. So you can immediately see which letter you must select to access the map.
As it was still so beautiful? "The first and last thing everyone needs" at least in the area of card reader ...
