I needed to edit hdpvr-video.c to add to add buf->urb->transfer_flags |= URB_NO_TRANSFER_DMA_MAP after the call to usb_fill_bulk_urb. Now I can capture just fine.
I noticed in the linux device driver book that line was added too.
the code block is:
usb_fill_bulk_urb(buf->urb, dev->udev,
usb_rcvbulkpipe(dev->udev,
dev->bulk_in_endpointAddr),
mem, dev->bulk_in_size,
hdpvr_read_bulk_callback, buf);
buf->urb->transfer_flags |= URB_NO_TRANSFER_DMA_MAP; // added JMM
buf->status = BUFSTAT_AVAILABLE;
HTH others
