for some cams, cia_info_version did not work.

As consequence we have the command :
en50221_app_pdu_send((en50221_app_t *)app, CICAM_AOT_PCMCIA_DATA_RATE, &rate, 1, 0);
(in file en50221_apps.c, function en50221_app_appinfo_handle)
Will hang the CAM.

I had to comment out lines 372 to 374 , in wating for a proper solution.
