Photon unable to be flashed over USB

Troubleshooting
1

I have a Photon that I need to flash over a USB connection using a MAC.

Now with the LED flashing YELLOW. I do the dfu-util command and get:

$ dfu-util -l
dfu-util 0.7

Found DFU: [2b04:d006] devnum=0, cfg=1, intf=0, alt=0, name="@Internal Flash /0x08000000/03016Ka,01016Kg,01064Kg,07128Kg"**
Found DFU: [2b04:d006] devnum=0, cfg=1, intf=0, alt=1, name="@DCT Flash /0x00000000/01016Kg"*

So all seems well…

Next I try to flash over usb

$ particle flash usb photon_firmware_1486312357348.bin
Including:
photon_firmware_1486312357348.bin
attempting to flash firmware to your device usb
Flash device failed
I didn’t recognize that device name or ID, try opening https://api.particle.io/v1/devices?access_token=`my_secert_ptr_to_api_tokens_etc

Now when I open this link up I see the device its Device ID is correct.

So what do I do to get the particle command line to flash over usb again?

I have to go this route as the program has a WiFi setup wrong so the Photon cannot be flashed via cloud.

HI All,

Was a simple command line error.

the flash command should have been…

particle flash -usb photon_firmware_148631235677.bin

Another case of cockpit error.

I think you still have an error - at least in this post.
You need two dashes for --usb

Hi ScruffR,
Yes you are correct the command is

particle flash --usb <photon.bin>
