WWAN card DW5811e on Dell E7450?

Hi! I cannot get this thing working in my E7450. Various people on the net say that it is possible to use this dw5811e in any laptop, I'm able to reflash this as generic one. But first it must be visible on the bus. In Linux and Windows it is not even detected. Am I doing something wrong, or some BIOS hack is needed to make this visible (vid/pid)?
