Turn Cubase Pro on first or last

Windows Pc/ Panorama P6 keyboards /Behringer X32 mixer/ Kemper profiler powerhead and last Cubase . The reason I ask sometimes they do not connect Properly . Does this matter which order they are switched on . Thanks British

I have the Panorama P1.

Usually I first start Cubase until the hub appears and then connect the Panorama and wait until it says it’s connected to Cubase. Then I continue loading my Cubase project.

Works every time for me.
