I am having a problem again flashing the photon . I am using linux Ubuntu 14 , I am sending you what I get in the terminal .
I put the photon in dfu mode (flashing yellow) and then I give the following commands
ioannis@ioannis-Inspiron-5547:~$ particle serial list
Found 1 device connected via serial:
/dev/ttyACM0 - Photon
ioannis@ioannis-Inspiron-5547:~$ particle flash --usb firmware.bin
Apparently I didn’t find a DFU device? util said dfu-util 0.8

Error writing firmware…no dfu device found.
Can you please help me on this because I now have 3 photons not working and want to flash them again.
