Does this rely to SDL?
Comment 1 Sam Lantinga 2021-01-19 16:46:58 UTC 
It does sound like an SDL issue. Any chance you can send me the headset for debugging? If not, any chance we can do remote interactive debugging over Zoom?
Comment 2 lukas 2021-01-27 19:24:36 UTC 
Hey Sam, I wrote an email to you but you didn't respond.

Of couse we can do remote debugging which would make a lot more sense than sending the headset from germany.

Those are the two products I could reproduce the bug with, just in case this helps you in general.

I'm available for debugging in the evenings from 6pm CET / 9am PST. But you can suggest a time of your choice.

I didn't get your e-mail for some reason. I just sent you e-mail, is now good?
Comment 4 Sam Lantinga 2021-01-27 20:38:44 UTC 
This is a bug in the driver for the USB device. It's hanging inside of this call:
    IDirectInput8_EnumDevices(dinput, DI8DEVCLASS_GAMECTRL, EnumJoysticksCallback, pContext, DIEDFL_ATTACHEDONLY);

Here is the stack trace showing a hang in the driver:
 	ntdll.dll!NtDeviceIoControlFile()	Unknown
 	KERNELBASE.dll!DeviceIoControl()	Unknown
 	kernel32.dll!DeviceIoControlImplementation()	Unknown
 	hid.dll!DeviceIoControlHelper()	Unknown
 	hid.dll!HidD_GetProductString()	Unknown
 	dinput8.dll!fGetProductStringFromDevice()	Unknown
 	dinput8.dll!CHid_GetProperty()	Unknown
 	dinput8.dll!CHid_GetDeviceInfo()	Unknown
 	dinput8.dll!CDIDev_GetDeviceInfoW()	Unknown
 	dinput8.dll!CDIDEnum_Next()	Unknown
 	dinput8.dll!CDIObj_EnumDevicesW()	Unknown

At this point there's nothing we can do in SDL other than disable DirectInput support.
