Dear Matthias and all:

Thank you for your advice.

I can't use "sdd".
Please see this...
--------
~/Desktop/gnuradio_fw$ sudo ./u2_flash_tool --dev=/dev/sdd -t fpga 
u2_rev3.bin -w
Traceback (most recent call last):
  File "./u2_flash_tool", line 111, in <module>
    main()
  File "./u2_flash_tool", line 98, in main
    and verify_flash(offset, filename, options.dev))
  File "./u2_flash_tool", line 35, in verify_flash
    dev_data = dev.read(len(file_data))
IOError: [Errno 5] Input/output error
~/Desktop/gnuradio_fw$ sudo ./u2_flash_tool --dev=/dev/sdd1 -t fpga 
u2_rev3.bin -w
---------

So I try this
---------
$ sudo u2_flash_tool --dev=/dev/sdd1 -t fpga u2_rev3-20100603.bin -w
$ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w
--------

After that, my USRP2's LED is not light up (all of 6 LEDs light OFF)
