Hi, I have got the Snow Leopard OS on my Macbook and want to use the CCID driver on it. But when I plug-in the reader, there is no any information. So I cancel the autostart of pcscd and run the command in the terminal: "pcscd -f". The reader can not be used and the terminal give the information "pcscd: posix_spawn: pcscd: No Such file or directory". But the reader can run successfully when I run the command "/usr/sbin/pcscd -f". So I want to know whether I must disable the autostart of pcscd if I want to use the reader on the Snow Leopard? Wait for your reply. Thank you. Best regards, Yongqing
