v0.9.2 MAINTENANCE

This is a maintenance release of xpadneo v0.9 to fix several issues found in the current v0.10 development branch.

Thanks to contributors Emil Velikov, @PetitMote, @Mikaka27 and @rdrms, we now have better compatibility with kernels 5.12 or later, latest DKMS versions, and improved documentation.

We also fixed an issue conforming to the Linux input spec better which improves compatibility with jinput and probably also the Chrome browser by not exposing keyboard mapping bits on a joystick device. Thanks to @markpaters for pointing that out.

Also, the current firmware generation seems to be unstable with our previous rumble throttling interval and we had to increase this to 50ms. This actually matches what the kernel is supposed to use for ff-memless emulation (but apparently it may still send rumble commands faster). Thus, it's recommended that anybody updates to this driver version.

Current kernels seem to cache devices when rebinding drivers. This affects our udev rules, and needed fixups won't be properly applied because the original VID/PID is no longer visible to us. We fixed this by reverting to the original VID/PID on device unbinding.

Due to the various compatibility fixes, this is a highly recommended update.

Compatibility issues

We found an issue with the OpenRGB and QMK Firmware projects which enabled world read/write permissions on rawhid devices unconditionally. While this may be a security issue on its own, it also enabled SDL to access our hidraw device in an incompatible way, leading to mapping problems for both axes and buttons, and also rumble instabilities. Both projects seem to have fixed this issue meanwhile but you may want to double-check you're updated to the latest versions, especially if you're experiencing issues with Steam Proton games.

Heads-up for package maintainers

Distributions shipping kernels 5.12 or later should no longer disable Bluetooth ERTM unconditionally. In fact, it may even harm connection stability when rumble is in use. For better stability, it's generally recommended to upgrade controllers to the new BLE firmware variant (version 5.x and above) for improved connection stability. To ease support, the firmware version will now be logged to dmesg with a warning if an old unstable firmware is found.

You should also inform users who experience input or rumble latency issues to adjust the Bluetooth latency parameters but this may be fixed in later bluez versions.
