GFIV - MKIII recognition problem.

[KPX]

Hi,
Found this in NJoy manual :
"""
2.4.12.PID control
If you use several VKB devices having same VID&PID you may have some troubles.
To avoid it change controller PID. Select Auto mode in USB PID group and set some
bias value. By default GNX controller has 231d/2234 VID/PID. If bias =3, then PID
becomes 2237. Check it using USBdeview.exe.
"""
In fact both GF (3 and 4) have the same VID/PID),but I cannot find how to change has written (auto mode not present).

Best regards
