VKB-SIM

Mamba Vintage + MCG Pro.
After installing MCGPro grip, some buttons from base (mixture,rdr trim, gear, flaps, start, pump m1, m2 batt) are not visible in Windows10 game controller (showing only 32 buttons) and DIYView.
All buttons are visible in VKB button tester and in sims like BOX and DCS, strange...? I wonder if they will be visible in other future sims such as MS Flightsimulator ect. if WIN10 cannot see them?

Neither in the Windows applet "Gaming Devices" nor in Wizzo you will see a button above the 32nd. Use the configurator or JoyTester to view all 128 buttons. It must be remembered that not every game is able to see so many buttons. For example, IL-2 sees 64, StarCitizen - 50, DCS, X-Plane - 128. I somehow did not think about it in FS2020, I need to check it.
