my g29 works well with assetto corsa 

the calibration of the G29 is correct with windows.
With G hub, the steering wheel is well detected.
When I enter GPL, I go to "options", and there, the "axis 0" steering wheel is not detected. GPL does not recognize it.
I restart several times, and "from time to time" it recognizes it.
This is what disturbs me. It's not like it doesn't work at all.
There may be a conflict between Windows and Gem+

thank you friends, don't apologize, if you repeat things, it doesn't matter.
Yes, my steering wheel is plugged into the "black" ports, not the blue ones.
I have assetto corsa installed, but I haven't tested it. I spent a lot of time with GPL to get to the championship.
Previously I had the LGS510 as a profiler installed, since I had a G27.
Switching to G29, as it didn't work, I uninstalled the profiler.
Windows does not recognize the G29 in devices UNLESS I install G hub.
Many people say a lot of bad things about G hub.
At home, impossible to operate the steering wheel without installing G hub.
If you read my posts carefully, what seems strange to me is the fact that GPL sometimes works with the G29.
This is why I am convinced, despite my many computer skills shortcomings, that the problem comes from Windows.

as you probably saw on the Blandford F2 topic, I couldn't get the G29 to work!
Having tried everything, whether with you, with the friends of GPL racer, Gleague or oAo, no solution to my problem.
I suspect Windows is causing my problems.
The driver is well recognized in devices.
I tested all versions of G hub.
the steering wheel works from time to time, and when it works I can drive for hours without problem.
As soon as I restart the PC, it no longer works.

I obviously did tests with the PS3 and PS4 button.
The steering wheel is well recognized in drivers.
I can calibrate it without problems.
I have to install G hub to make it work.
When starting the PC, the steering wheel works from time to time, online or offline. I can drive without problems.
As soon as I restart the PC, nothing works anymore.

as you no doubt noticed, I did not participate at the start of the championships.
I have big problems with the G29.
Of course I tried everything, I explained my problem on all the GPL forums.
I am now firmly convinced that my problem is with windows 10.
there is a conflict somewhere.
The only thing I haven't tried is formatting my PC.
It is very difficult here in Cambodia to find steering wheels. We ONLY find G29s.
So I decided to give up, this story really tired me out. It almost drove me crazy!
Good luck to everyone

a huge thank you to Sergio, from GPL racer 

above the steering wheel, there is a very small switch, it was on PS4, it had to be positioned on PS3!! 

The steering wheel works great!

Thank you all for your help

Therefore, this resolution of the problem should be kept in the archives, it could be useful to someone else

yes, I also calibrated the steering wheel in GPL.

to summarize the situation: since 2013, I have been doing GPL with a G25, G27,  ts-pc racer, I have never experienced this problem.

Since I live in Cambodia, I bought a G29 (that's the only thing you can find here)!

So I managed to install the steering wheel, but I have this problem with the engine running at full speed.
That said, it seems that I have found the solution: before entering the track, I go to "options", and I turn the steering wheel once.
The problem disappeared by doing this. I tested several times, with several mods

in windows, I have the correct controller displayed

yes I checked, USB port 2 

I have a big problem when I enter the track, the wheels are turned to the left, and the car engine is running at full speed.
Impossible to control the car.
All mods are affected.
The problem occurs online and offline.
Can you please help me resolve this issue?
THANKS

Hi Axel,
no, because the problem is different.
the G25 and G27 work great.
the G29 works very well too, but WITHOUT the shifter. Those who ride without the shifter, everything is fine.
The G29 shifter is not fully recognized in GPL; you need to modify the configuration in GPL shift.
I'm looking for someone who had the same problem, and who modified their GPL shift.

Thx

in fact, the adjustment is done in GPLshift, concerning the G29.
Could someone who uses the shifter with the G29 give me their GPL shift?

yes, the steering wheel works.
I use the shifter, and for it to work, you have to use GPLshift, or fairshift.
I don't know the settings in these 2 cases
