So I assume these effects are done on the cmedia chip, not in software. The Linux drivers can only do the standard stuff, although the sources indicate that there are some extended registers, possibly used for the 3d processing. I'd like to figure out how the 3d processing works by monitoring the data sent by the windows driver to those registers and then try to resend that data under Linux. For figuring out my HP3300c scanner I used a tool called USB snoopy that helps monitor the traffic between driver and scanner over the USB bus. Is there a similar tool for PCI? Kind regards, Bertrik Sikken
