There are trackpoint devices that fail to respond to the PS2 command PSMOUSE_CMD_GETID if immediately queried after the parent device is deactivated. Add a small delay for the hardware to get in a sane state before sending any PS2 commands. One example of such a system is: Lenovo ThinkPad X120e, model 30515QG synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x121c00, board id: 1811, fw id: 797391 Signed-off-by: Stefan Assmann <sassmann@kpanic.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
