     * To debug Device you can def the following :
     * #define DEBUG_HWDEVICE
     *   Activate debug mechanism:
     *     - Add more trace
     *     - All computation done by device are checked by default device.
     *       Required IODUMMYCRYPT_HWDEVICE or IONOCRYPT_HWDEVICE for fully working
     * #define IODUMMYCRYPT_HWDEVICE 1
     *     - It assumes sensitive data encryption is is off on device side. a XOR with 0x55. This allow Ledger Class to make check on clear value
     * #define IONOCRYPT_HWDEVICE 1
     *     - It assumes sensitive data encryption is off on device side.
