Vive Pro Headset cannot connect to USB 3.0

[Landerholm]

Hi, 

Today I tried to install the new Vive Pro Headset on two diffrent HP Workstations (my normal VR machines).

It´s a Z8 with dual P6000 and dual Xeon 18 cores CPUs, the other is a Z4, 14 cores Core i9 X with a P5000...

Both have several USB 3.0 and also USB 3.1 (with and without power) none of them works when I try to connect the headset.? Any Ideas?

(I have a huge VR presentation on monday 22nd, for all major HP resellers in sweden and had planned to show them the new glasses insted of the old ones.)

Thanks for input in advance
