Why doesn't Canon make drivers for using the digital video camera with a computer?

The driver for downloading digital video data from the camera must support the interface card, not the camera. As long as the card supports IEEE-1394 (firewire) data transfer, the computer will be able to download data from the Canon digital video camera using the driver for the card. Models equipped with the separate USB port come with the Canon Digital Video Solution Disk, which contains USB drivers and image editing software for still images only.
