Since I'm a bit keen on actually being able to read the cards I already
own I have another suggestion. 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
