I see that there was an issue with the changes made to support GameCube controllers. http://lists.libsdl.org/pipermail/commits-libsdl.org/2019-June/003998.html
“It causes the HIDAPI devices to always be opened on enumeration, which causes crashes in the Windows drivers when multiple applications are reading and writing at the same time. We can revisit this after 2.0.10 release.”
I couldn’t find a bug report on this issue. I’d like to fix whatever problems there were with the driver if someone could point me to the right direction.
