CORRECTThis is what is known, I believe, as the Intel standard.
There is another standard used on many motherboards, such as PCChips M755:
as follows (using YOUR pin numbering scheme of 1 to 10)
1-Vcc; 3-NC;5-D1-;7-D1+;9=GND
2-GND;4-D2+;6-D2-;8-NC;10-Vcc
normally implemented as TWO 5-pin connectors

CORRECTOh, its right, I think. On all internal cardreaders I have seen this pinout is right.APPROVED
