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? =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart1804530.P6yahemBsi Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlW7qWoACgkQi/DJPQPkQ1L7GQCgiDirXiuW8CPyPCoNMeC6+I6v gB4An2LwZ+AWMQLEh/snRqzdJZ5uIdgP =A1mL -----END PGP SIGNATURE----- --nextPart1804530.P6yahemBsi--
