Hello,
I am trying to implement multigrabber support in bttvx
(http://argo.lira.dist.unige.it/cbeltran/bttvx.htm); but I am having some
problems with the pci_attach_device(…) function.
I have two cards with bt878 chips and they are detected correctly when a do
“pci -v” from a shell. But when I invoke pci_attach_device(…) from my
code, only one of the cards is detected. I am using the code suggested in
“Talking to hardware under neutrino”, and the result of pci -v is the next:
