With -x: $ grep ^pms dmesg.boot pms0 at pckbc2 (aux slot) pms0: synaptics_probe: Not synaptics. pms0: reset 0 0xaa 0x00 It's not synaptics, but in an older log that I shared Linux did treat it as so. So not sure it's kind-of-compatible-but-not-fully or so. And is there any way to try this hypothesis out? -- Mayuresh
