Hi! Automatic detection of BYD touchpads was sadly disabled at the end of last year. They can be still be used by forcing the protocol manually as described by Kai-Heng Feng above.
The reason for disabling detection was that the detection code generated false positives with normal PS/2 mice (meaning that some people's normal mice didn't work, because they were detected as BYD touchpads instead). This obviously isn't good. I investigated using DMI data to restrict probing to only machines which have that touchpad. However, the values were too generic - see https://patchwork.kernel.org/patch/9423801/ The patch disabling probing is here: https://patchwork.kernel.org/patch/9424421/ Potential solutions are: - Persuade OEMs shipping these touchpads to provide sensible DMI values - Experiment with the driver to see if the touchpad will identify itself reliably *in a way which can't be interpreted as normal PS/2 commands by a PS/2 mouse*.
