Who knows...
Like I said, I get around 330 Kbytes/s in card reader integrated in
printer. It is still much higher that what I get with this driver....

I will figure that out sooner or later.

Btw, your cards aren't Type M, right?
However I use here a Type M card, and its likely to include an FTL
inside, thus, it might explain the low speeds I get there partially...

Best regards,
