Hi maurizio,

If you have disable the JTAG support in the MAX7000S device, then you cannot use the JTAG port for programming once you program the .pof file.

After the 1st programming, this option will disable the JTAG port to any subsequent programming. In this case, you need to use 3rd party programming such as DATA IO , BP programmer etc that support Altera device programming. If you intend to reprogram the MAX7000S multiple times via JTAG port with usbblaster, then you need to enable the JTAG support option. Otherwise you need to use 3rd party programmer to program the MAX7000S device.
