I bought a Logitech F710 just to test out the haptic support for DirectInput in SDL, and sadly it does not work. Testhaptic.exe detects the effects and tries to play a sine effect, but errors out saying that the effect cannot be created. Basic rumble does work when the device is in XInput mode, so I'm guessing it isn't a problem with the joystick. I have the Logitech Gaming Software installed and haptics work in their test as well.

I also tried nabbing the latest code from the HG repository from after the separation of the DInput and XInput code, but that failed as well. The problem seems to be in the CreateNewEffect call to DirectInput that errors out with an INVALIDPARAM.

I experience something related with the Logitech MOMO Racing wheel.
In addition, SDL_HapticOpenFromJoystick() fails with SDL_Error: "Haptic error Setting cooperative level to exclusive",
The device can be opened via SDL_HapticOpen(), but then I see the CreateNewEffect error described here. I have tried with 2.0.0, 2.0.1, 2.0.2, 2.0.3, & tip. None work.

I downloaded the Motioninjoy driver for my Dual Shock 3 that allows it to operate in DirectInput mode with rumble support and I get the same error. So it doesn't seem to be specific to the Logitech.

I've found this bug as well, the problem is the XInput haptics driver takes values maxing out at 64K while SDL maxes at 32K. There IS a very faint rumble but it's barely noticable. I attached a patch that fixes the problem. More info here: https://discourse.libsdl.org/t/patch-low-magnitudes-with-xinput-haptics/22551
