Start out using a zero OCR. If no card responds using this we try again using the bit mask created in this patch. That would get compliant cards using the first go and the rest using the second. If someone tries to combine faulty cards with good ones on the same bus the faulty ones will of course not work but at least people have the chance of getting them to work when inserted by themselves. Does this sound like a solution that would work? I'd be happy to write the code and test it with the cards I have at my disposal. Rgds Pierre
