I can't seem to add a device, either through the particle.io web or toolset.
PS C:\Users\Dennis> particle identify
Your device id is 400032000447343337373739
PS C:\Users\Dennis> particle device add
Please specify a device id
PS C:\Users\Dennis> particle device add 400032000447343337373739
Claiming device 400032000447343337373739
Failed to claim device, server said { ok: false, errors: [ 'device does not exist' ] }
Any help greatly appreciated. I have already did a particle update and updated to latest firmware via usb serial.
I took a look at our logs and the device is having problems handshaking. You should try putting the device into DFU mode and then running particle keys doctor.
