Hi,
I suspect that the absence in DMA read support probably explains why
this would be so CPU intensive.
I have a DMA read routine working for my cpia camera, but am having
trouble adapting it to the general parport driver. I sent a message
about my problems a few months ago, but got no replies. If any parport
gurus were willing to give me a hand it should be possible to get the
routine working with very little work.
