Or are you referring to the fact that the device should show up as a proper v4l2 device to userspace, and not need a custom userspace program interface? > I hope this list is the correct place for this suggestion, feel free to > forward it to another place. It's a good place, hopefully people who wish to help out with this will contact you. But note, without specs, this will be a lot of work :) good luck, greg k-h
