Exactly, I used to use Omnikey readers too but I had to gave up due to this problem. On Windows Omnikey's driver uses proprietary escape codes to make it work: /* We employ a hack for Omnikey readers which are able to send TPDUs using an escape sequence. There is no documentation but the Windows driver does it this way. Tested using a CM6121. This method works also for the Cherry XX44 keyboards; however there are problems with the ccid_transceive_secure which leads to a loss of sync on the CCID level. If Cherry wants to make their keyboard work again, they should hand over some docs. */ The 6121 is a PCMCIA style reader which I could make work for my old laptop. As usual with reader vendors they use their ASICs for all types of readers and thus he sees the problem also with the 3121. I have an 5121 here but I can use it only for RFID. He may be able to use the 3121 with ECC keys. Shalom-Salam, Werner -- Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
