Hi Richard!
I just got my crosshair delivered, plugged it to the PC and configured it apparently without issues and with the following results:
Cross Hair Help Information
----------------------------
Manager Ver:4.5.26
GameEngine Ver:2.0.0
Macro Ver:1.10.0
Hardware Ver:1.7.6
Firmware Ver:4.5.26
BootLoader Ver:2.3.0
SN:38-00-25-00-17-47-37-31-30-35-36-39
Once the firmware was updated and the device recognized by the PC I was able to select Gran Turismo Sport, Steering Wheel Logitech G25, set it to start up, saved, connected to the PS4 checking all connections following the guides, turned off the controller, it all seemed good, however, I am getting a RGB cycling logo
I checked the Warning and Solutions pdf and the steering wheel pdf guide, no luck, what could be wrong?
