PV-155 shares the same PCI ID as PV-149, but require a different > entry, then we shouldn't add it to the PV-150 autodetection code. > Okay. You can easily access four ports on the PV-155 / PV-981, but to access the sub (/dev/videoX,1-3) channels you need to add the modprobe line. > The better would be to check with the manufacturer if is there a > way to detect between those two boards (maybe reading eeprom?). > > I can find out, but getting technical data from Provideo can be more painful then pulling teeth. > Why do you need the card= parameter, if it shares the same subsystem > ID as the other PV-981 models? I think I explained that about with the sub channels, if I'm missing something let me know. Thanks! -- -- Curtis Hall (curt@bluecherry.net) Bluecherry - www.bluecherry.net (877) 418-3391 x 201
