Hello, here is output from dmesg for psmouse.ko [ 266.378751] psmouse: calling psmouse_init() [ 267.167150] psmouse serio1: synaptics: queried max coordinates: x [..5676], y [..4758] [ 267.198416] psmouse serio1: synaptics: queried min coordinates: x [1266..], y [1096..] [ 267.260402] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xf002a3/0x943300/0x12e800, board id: 3072, fw id: 2560 [ 267.260418] psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0 [ 267.299629] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input39 [ 268.697333] psmouse serio4: cypress_ps2: send extension cmd 0x00, [0 0 0 0] [ 269.259351] psmouse serio4: cypress_ps2: Command 0x00 response data (0x): 00 00 14 [ 269.562762] psmouse serio4: alps: E6 report: 00 00 64 [ 269.825915] psmouse serio4: alps: E7 report: 10 00 64 [ 270.086671] psmouse serio4: alps: EC report: 10 00 64 [ 270.125866] psmouse serio4: alps: Likely not an ALPS touchpad: E7=10 00 64, EC=10 00 64 [ 270.388147] psmouse serio4: elantech: unexpected magic knock result 0x00, 0x02, 0x64. [ 271.390241] psmouse serio4: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3 [ 271.586156] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/serio4/input/input40 As you can see it takes about 5 seconds to initialize TrackPoint input device. And about 3 seconds from stage after synaptics export serio device. I think this is just because of trying to detect device type. Is there any way how to speed it up? Maybe for synaptics serio devices try to probe for TPPS/2 at first? -- Pali Rohár pali.rohar@xxxxxxxxx
