Issues you say ? It's been many many hours since I first connected the wheel base and everything.
I did all the firmware updates with no issues at all. But ... impossible to get the wheel AND pedals do anything on track. What am I missing ? The usb cable is connected, I tried also a port at the back of the PS5, nothing. There is only the PS button and square/circle/triangle/cross that seam to do something. There is not a single input coming from pedals and wheel. But on the PC with the software to test it, everything works. Also, I tried GT Sport on PS4 (with GT DD Pro at the right PS4 mode), same result, no input at all on track.
As a reference, this is the GT DD Pro regular kit that is plugged at the moment. I did not tried the 8nm I bought, nor the load cell which is still in the box. I told myself that the base kit should do the work at first, right ?
This is a many many many $$$ rig not worth a penny at the moment.
EDIT: well, not sure if it's the fact that I started to unplug and plug back everything (first the RJ12 from behind the wheel base).
OR .. like you said
slthree too basic ?! Probably that. Sad because I asked myself already in the game "well, now how to select the wheel ..." to never found it in the game itself ! You need to realize that just aside the PS5, I have a PS3. For a couple months now I'm playing regularly with GT5 on PS3, with a wheel. The thing is that I only need to turn on the PS3 and the game, plug the USB cable from the wheel and it's working. The problem maybe is that I got accustomed to that behavior and as basic as it is on PS5, the "controller" (wheel !) button never really crossed my mind.
Enough complaining, now time to do some lapping
