So here we are, I installed Haiku 32bit beta1 on a different hw in which works nearly everything. I put inside the card, moved the driver bt848 in /boot/home/config/non-packaged/add-ons/kernel/drivers/bin as beOS did, linked it in /boot/home/config/non-packaged/add-ons/kernel/drivers/dev/video/bt848
put the add-on bt848.media_addon in /boot/home/config/non-packaged/add-ons/media. Rebooted.
configured media preferences to use the right video input source (if I don’t do it codycam says in the central box that there’s no webcam connected)
Started codycam and the central box it’s completely empty, no signal, no pictures no text.
Syslog shows no errors at all (except that the card is called Bt878)
Gonna do it
