Unable to use gamepad 2 without connecting gamepad 1 first (Xbox Series Controller)

[chef-wally]

Description

I use two Controller (Xbox One For Windows) connected via the Xbox Wireless Adapter for Windows. The issue I am experiencing is that when connecting gamepad 1 first then gamepad 2 and if gamepad 1 disconnects (sleep/suspend) gamepad 2 will get the Instance Guid of gamepad 1 and this will cause gamepad 2 to not work in RetroArch. The solution is to turn gamepad 1 back on.

I tried to find a unique identifier for the gamepads to resolve the issue outside of RetroArch by using the Instance Guid. However, gamepad 1 will always be {170c5400-59e9-11ee-8001-444553540000} and then the gamepad 2 {55ae4380-59e9-11ee-8001-444553540000} with the Xbox Wireless Adapter for Windows. So when gamepad 1 disconnects the Instance Guid of gamepad 2 will become the Instance Guid of gamepad 1 and won't work in RetroArch unless you turn gamepad 1 back on.

I then tried to utilise the Device Instance Path however, the values after HID\VID_045E&PID_0B12&IG_00<Id> are not unique and change constantly.

Expected behavior

If you turn off gamepad 1 (Port 1 Controls), then gamepad 2 (Port 2 Controls) should still work without having to turn on gamepad 1 again.

Actual behavior

If you have both gamepads connected, then gamepad 1 (Port 1 Controls) disconnects (sleep/suspend/turned off to save battery), then gamepad 2 (Port 2 Controls) won't work unless you turn gamepad 1 back on.

Steps to reproduce the bug

1. retroarch.cfg is set as input_player1_joypad_index = "0" and input_player2_joypad_index = "1"
2. Connect gamepad 1 (Port 1 Controls) then gamepad 2 (Port 2 Controls)
3. RetroArch menu says Port 1 Controls is "Xbox Series Controller (1)" and Port 2 Controls is "Xbox Series Controller (2)"
4. Disconnect gamepad 1 "Xbox Series Controller (1)". Now gamepad 2 becomes "Xbox Series Controller" under Port 1 Controls and does not work
5. Solution, turn gamepad 1 back on

I guess I encountered the same problem.
I use moonlight, but when the moonlight is disconnected, the gamepad is lost, causing the RA controller to become unusable.
