The folio keyboard of the Z13 can get stuck in its BIOS mode, where the
touchpad behaves like a mouse and the keyboard start button is not
reliable if we perform the initialization too quickly. This mostly
happens during boot, and can be verified to be caused by hid-asus
through simple blacklisting. A small delay fixes it.

See my comment on patch 1 about trying a loop with the init
request/response as a hopeful way to test readiness.
