I have two Photon “Internet Buttons”. They both are connected to the cloud and can be programmed through the IDE. Now I’m trying to update the firmware from 0.4.9 to 0.6.1 on both using the Particle Firmware Manager, which should detect them when plugged into USB and in DFU mode (they do blink Yellow). I put them in DFU mode and they don’t appear in the Mac’s USB device list (via System Report or “ioreg -p IOUSB” in Terminal). Therefore, Particle Firmware Manager doesn’t find them and keeps asking to “Connect a Particle Device using a USB cable”.
