I cannot get the driver to work when using a SDHC Samsung Evo 16GB (placed inside a card reader), it always report the following (1). If I now place the card onto a USB reader (USB-HUB reader) then everything is fine (tested using f3: f3probe). Are there any options I can switch to make the driver more tolerant with my hardware ?
