If the eeprom dump works well at the first time, but after usb V1.3.0.14 programmer disconnects and reconnects again, it shows usb device does not recognize again. You should try one of these two solutions:
1). You should fill eeprom with FF. After connecting it, it will ask you to update eeprom. You should update and it will work well.
2). You need to change this N15. N15 is fuse, value about 0R.
The problem is solved.
