Description Mathieu Laurendeau 2017-01-17 08:15:15 UTC 
This issue was reported on the GIMX forum: https://forum.gimx.fr/viewtopic.php?f=5&t=1976

I think this is a regression introduced in SDL 2.0.4 due to bug 2460. Bug 3005 also was a related regression.

My assumption is that the joystick device in question has type DI8DEVTYPE_SUPPLEMENTAL and subtype DI8DEVTYPESUPPLEMENTAL_THREEPEDALS.

> DI8DEVTYPE_SUPPLEMENTAL

> Specialized device with functionality unsuitable for the main control of an
> application, such as pedals used with a wheel.

Comment 3 Mathieu Laurendeau 2017-01-19 08:52:12 UTC 
Thanks.
I can confirm that removing the filtering on devtype fixed the issue reported on the GIMX forum.

You probably forgot to remove the should_ignore variable since it is not used.

Yep, got that, thanks.
