[Solved] dfu-util does not recognize Particle Photon; works on Mac

jernst · 2016-12-15 04:50:47

When connected via USB,

dfu-util -l

is supposed to list the Particle Photon [1], but it does not on Arch. It works with the same version of dfu-util on the Mac.

The device is being created as

crw-rw-rw- 1 root uucp 166, 0 Dec 15 04:44 /dev/ttyACM0

lsusb -v

shows it as:

Any ideas?

random guess, did you try to sudo it? (at least you need UID to write to the device, but I don't know whether that's required for the call)

jernst · 2016-12-15 17:26:24

Permissions was my first, guess, too, but that's not it. No change when executed as root.

You need to enable DFU mode on Photon to let dfu-util recognize it.

Thanks, @mathben. You are correct. Sorry about this, operator error.
