Hello, I am developping a driver for a usb hid device(smart card) using IOkit kext(driver from kernel side).I need to select a elementary file EF 0x100, to read the URL stored in it.The APDU command is 80 A4 00 00 02 01 00.I have overrided the methods of IOUSBHIDDriver, I have tried the methods like exchangeAPDU and Transmit, but these are not supported in the kernel. Can anyone please help me how to send this command to the device. thank you _______________________________________________ Priya TIROUNARAYANANE - Dévéloppeuse d'application iNet System Tel : 01 46 23 04 06 Fax : 01 46 23 06 32 Mailto:priya@inet-system.fr http://www.inet-system.fr Merci de penser à l'environnement avant d'imprimer ce courriel
