Hi, I'm using a cyberflex card and a O2 Micro reader and PCSC lite 0.8.4. I am trying to create an EF in the Master file. I 'm able to read the MF's ACL (the result is : 1 0 0 FF FF 0 0 0). That's mean auth0 and auth1 have all the priviledges on the Master File isn't it ? Default can only list the directory and others has no right at all. So i verify the key for both of them (auth0, auth1). I get a successful answer. (90 00) for both of them. However everytime i try to create an EF i got the answer 0x69, 0x82, meaning insufficient priviledge. So I don't understand why since i verify the key before, did i miss something ? Any Idea ? Other things : Is the chip drive reader and towitoko driver are compatible with the cyberflex access Card ? I was wondering because when i use my code(select file) with SLE4428 and chip drive and towitoko it works well. When i use cyberflex and O2 Micro reader it works well. But if i use cyberflex, chip drive it does not work well. Is that normal ? -- Christian Jean +-------------------------------+-----------------------------+ |R&D Engineer |Tel : (65) 844 1301 | |celestix Networks Pte Ltd |Fax : (65) 844 1125 | |18 Tannery Lane #05-03 |mail: [EMAIL PROTECTED] | |Lian Tong Building |web : http://www.celestix.com| |Singapore 347780 | | +-------------------------------+-----------------------------+ *************************************************************** Linux Smart Card Developers - M.U.S.C.L.E.
