Having the same issue.
Vive-Pro: green light and works fine on PC#1 (Windows 7 Pro) / GTX 980
Same exact HMD with associated cables, etc.
Vive-Pro: red light on PC#2 (Windows 10 Home) / GTX 1080 Ti
In device manager, under 'Other devices', the same 'BCM2045A0' is coming up as "no compatible drivers for this device."
I've already:
* uninstalled all drivers, reseated cables, drivers auto-loaded (except for the above)
* specifically uninstalled the BCM.. from device manager and updated (no driver found)
Google shows that this driver on Dell.com as a download but then Windows 10 complains that this is not supported. Help?
