8BitDo Pro 2 Controller Xinput mode hangs during game launch

[Mav3r1ckHL]

System Specs:
AMD Ryzen 9 5900X
32GB RAM
NVIDIA 1080Ti
8BitDo Pro 2 Controller connected via a wired connection (USB-C to USB 2.0)

Context:

This specific controller has the ability to switch between different modes of operation from Xinput, Dinput, Android and Nintendo Switch.

Details:

When attempting to launch any game using the default Xinput setup the 8BitDo Pro2 Controller will cause the emulator to hang (not respond). Only after disconnecting the controller (either physically or switching mode of operation) will the emulator stop hanging and proceed to launch the game. Reconnecting the controller afterwards (switching back to xinput) allows the end user to regain control of the game.

NOTE: Direct Input mode of operation works without any issues from what I can observe. Logs have been attached.

I've actually bought this controller recently and can confirm that it hangs when I am connected via USB in XInput mode.
The main thread is stuck in libusb_list_devices until I disconnect the controller.
The input itself works as usual, it's just the unrelated libusb call that causes these headaches.

It looks like this is either a libusb bug or a firmware issue.
Sadly updating to the latest firmware (v.1.0.8 I think) does not fix this either.

This may be resolved with 8bitdo firmware v 2.01.
For me it doesn't connect to XInput in USB mode at all with that firmware, but it works in SDL, so I'll just close this issue.

Nevermind. I connected it to a different USB port and now it shows up again.
Still broken even with SDL
