Good Morning, I was reaching out to report that there's been a regression in the latest stable 6.9.4 kernel. I'm using Fedora 40 and 6.9.4 just got pushed to the repos recently. Upon updating, my wired USB Xinput controllers no longer get detected. I've tried two 8BitDo controllers, the one being the 8BitDo Pro 2 Bluetooth (with a USB cable) and the other being the 8BitDo Pro 2 Wired Controller for Xbox. Neither of them are being detected on Kernel 6.9.4, despite previously working throughout the lifetime of Fedora 40's 6.8.x kernel versions, the latest being 6.8.11. I've also tried the vanilla kernel, as well as the latest vanilla mainline kernel from Fedora's COPR: 6.10.0-0.rc4.337.vanilla.fc40.x86_64. To reproduce, simply load Kernel 6.9.4+ and plug a USB controller in with XInput (either an Xbox controller or something else that emulates one). It won't be detected. I plugged in a PS5 controller and it worked, but when I plugged in an Xbox Series S controller, it didn't work. The 8BitDo Pro 2 Bluetooth controller has four different settings (Switch, Android, DirectInput, Xinput), and it was detected and worked on every setting except for the Xinput setting. Reverting to version 6.8.11 fixes the issues immediately. -- Respectfully, Edward Wawrzynski
