could not upload code : No device found on cu.usbmodem1421

Official Hardware Mega Due

Hi,

I am trying to use Arduino DUE R3 on my MAC OS 10.10.2.
And I am using the latest Arduino IDE 1.6.5.

I was successfully upload the code when the very first time, after that , it suddently not working anymore.
try erase and reset , still not working.

The message I got from the verbose mode is :

Sketch uses 10,500 bytes (2%) of program storage space. Maximum is 524,288 bytes.
Forcing reset using 1200bps open/close on port /dev/cu.usbmodem1421
/Users/stevenchai/Library/Arduino15/packages/arduino/tools/bossac/1.3a-arduino/bossac -i -d --port=cu.usbmodem1421 -U false -e -w -v -b /var/folders/j_/k3hwp1fj4313c566br3q33h40000gn/T/build8842044797433724118.tmp/sketch_jul06a.cpp.bin -R
Send auto-baud
No device found on cu.usbmodem1421

Could anyone give me any clue? Thanks~
