What is needed to to find out how that BYD's kernel driver detect if device is normal PS/2 mouse connected to ordinary PS/2 port, or if it is PS/2 BYD touched. Microsoft has only preinstalled genetic PS/2 driver, so touchpad is probably working as ordinary mouse (if that BYD's kernel driver is not installed). > The only publicly available info on these can be found here: > > 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 engineer or sniff data exchange from windows driver. -- Pali Rohár pali.rohar@xxxxxxxxx
