Yes, that is expected. What is needed to to find out how that BYD's=20 kernel driver detect if device is normal PS/2 mouse connected to=20 ordinary PS/2 port, or if it is PS/2 BYD touched. Microsoft has only preinstalled genetic PS/2 driver, so touchpad is=20 probably working as ordinary mouse (if that BYD's kernel driver is not=20 installed). > The only publicly available info on these can be found here: >=20 > http://bydit.com/doce/products/microelectronics/2474.html Webserver is really slow...

No info there regarding protocol, etc. I understand... it is hard to get some information... One option is to trying to ask BYD again, another is to try reverse=20 engineer or sniff data exchange from windows driver. =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart4207773.ug2hyLgHpE 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) iEYEABECAAYFAlgnVd0ACgkQi/DJPQPkQ1LUaACeOsOoeoaxMMybC8EP3aISAK0K SPQAn1xjufqmO8RS0+taidK8yNqXzvu3 =Y+60 -----END PGP SIGNATURE----- --nextPart4207773.ug2hyLgHpE--
