Windows can't see buttons

[isawben]

I built a button box with 17 buttons, setup the pins in configurator, changed the name to 'Button Box', wrote the config to the device, verified in configurator that the buttons do work but in windows game controller settings, no buttons are displayed. In games, only the axes and sliders are recognized but I can't use them.

If I disable the output on all the axes then windows sees 1 button, but I can't activate it. Configurator still sees all buttons as working, but windows only sees 1 and it doesn't work, but now games also show this 1 button that doesn't work and the axes I disabled.

I also have a Logitech G920 wheel and a chinese shifter that seems to use a generic USB joystick controller, like the zero delay boards. The issue persists if I unplug those and have only the button box. I also tried changing the VID/PID.

Using 1.7.1b3

I originally built the button box with a zero delay USB joystick encoder board and that worked fine. Then I bought the shifter, which is a no name chinese made device which has an identical hardware name and PID as the zero delay board. It's quite nice really, except some games (BeamNG.Drive in particular) treat identically named devices as the same device so I couldn't separate the inputs or bind them to different controls. So I stumbled on FreeJoy and was instantly impressed with the flexibility. I ordered the bluepill right away. Today a finally rebuilt the button box and am saddened I can't get it to work.
