Which one? All GT-6801-based scanners I know about are supported by the gt68xx-Backend (see http://www.meier-geinitz.de/sane/gt68xx-backend/). If you have yet another scanner that uses this chip, I would like to know about it. I guess you should start with the gt68xx backend. > But I have not Gt6801 chip specification, So i don't know how backend > communicate with scanner. Who has documents about this? Thanks The only thing that seems to be available publically is the short specification on: http://www.sunnic.com.tw/components/grand%20tecrl/90_grandtech/1/grandtech_h_1_con.htm The GT6816 specification goes into more detail, and those chips aren't that different. However, both of these files won't be very useful for you. What you need, would be a specification of the firmware of your scanner, because that's what you use when you communicate with the scanner. I don't have a specification, but the Mustek code mentioned on my page has at least a header file that describes the commands a little bit. Bye, Henning
