    More information can be found <a href="http://gkall.hobby.nl/gt8911-grandtech.html">on this

      page</a>. Maybe once there will be SANE support for this device?
 | 
			
		||||
    Dual mode chip, see the www.gphoto.org for the still camera function (camlib pdc640), 
 |

    chip is also used in many other cameras/webcams.

      and/or <em>cat /proc/scsi/scsi</em> (for SCSI scanners) or <em>cat

      /proc/bus/usb/devices</em> (for USB scanners) can help. If you dare to

      open the scanner, have a look at the text that's printed on the

      scanner is similar to another one (e.g. supported by the same Windows
