USB CCID Communication Problem

   I am developing an application in which the FRDM-K82F will transfer data to the front end software using USB CCID command.


 I successfully convert the USB-CCID code from K64(K64 USB CCID demo.) to K82, and the windows recognized the K82 board as "Microsoft USBCCID smart card reader".


The windows is sending GET_SLOTSTATUS command and K82 reply to this command. After this windows is sending ICC_POWERON command and the K82 reply to this command also. 


Then the windows is sending ICC_POWEROFF command and the K82 reply to it,  (after that the process is in loop like POWERON , POWEROFF). I am unable to proceed any data communication.


Please anyone help me to solve this issue.


Thanks & Regards,
