Cant add devices

For some reason I am unable to add devices I can create customers but i cant create devices.

I would also like the ability to have one page where I can create a new job, customer and device with model. I need to beable to add new devices on the fly with job creation.

Hey please send more details of error which you receive when you try to add a Device.

Also please note you have to add device and assign it to a brand incase you want that to be visible in job dropdown list.
