Sorry it took me so long to read your reply, i tested it, here's my video testing it
So for the current 1.0.5 change, when i open the app with xinput mode, it detects. When i change it to DirectInput mode without closing the app, it will detects the DirectInput input. But when i close the app, and re-open it while in DirectInput mode, it won't read any input (no hightlight on the controller UI nor any text appear), and in this state, even when i change to xinput mode, it doesn't read anything. I need to close it, then re open it in xinput mode in order for it to work.
This also happen when i unplug & re-plug the controller. If the software were being launched during the xinput mode, it'll always read the input. The input won't be read if i launch the software during directinput mode, even if i unplug & re-plug the controller with xinput mode.
And these behavior above is the same in 1.0.4 (i checked it)
.
I know this won't be a priority for you, you don't have the device on your own to test it, and you might have other stuff to do in life. Don't worry, i won't push you, you did amazing by just providing this tool to everyone who needs it. You're an amazing developer✨
