@LOGI_Rich sorry to bother you here, but maybe you can help.
I have seen a similar report in a different forum and I've been trying to help there to get it to work, but so far to no avail.
It's the same issue as described above. Manual shifting is not possible in normal GT7 modes, but with some exceptions:
It does work in Sport Mode (as there the clutch and H-Shifters are disabled)
It works in the menu (so the buttons work)
It works on a freshly created account.
Changing the shifting commands to other buttons doesn't help.
The user there doesn't have an H-Shifter and he said that the wheel was already changed once, without change.
I don't know where this is but something on the software side of things has to be wrong, just no idea where. I pinged you just hoping that maybe you've already come across this issue and a potential fix.
The one thing that worries me a bit is that, in GT7, when you go check the wheel inputs (like the turn radius and pedal inputs), it shows as an Unknown device instead of a G923.
According to the user he tried all USB ports and no other HUBs etc. are put in between.
I have now asked the user to increase the deadzone of the clutch pedal within GT7 to see if this has any effect, that maybe the clutch activates itself causing this
