I run some tests with v1.7.5-549-g3cf6b1856

If the MSI XBOX Controller (xinput) is connected no other dinput connected controller is recognized.

I tried with 3 different dinput controllers (one at a time and then all connected together), all previously fully working if the MSI controller was not connected.
