That's because bash tries to redirect the output of 'sudo echo' to the
/sys/... file, but since bash runs without elevated privileges, it
cannot do so.

Do instead

  echo -n 1 |sudo tee /sys/devices/platform/i8042/serio0/serio2/press_to_se=
lect

or

  sudo sh -c 'echo -n 1 > /sys/devices/platform/i8042/serio0/serio2/press_t=
o_select'

or

  $ sudo -s
  # echo -n 1 >/sys/devices/platform/i8042/serio0/serio2/press_to_select
  # exit
  $

whichever is easier to remember.
