This machine is probably a Genesys Logic GL846 or 847, you would need to open the machine to be sure. The datasheet for those chips is not available online, but you can find the gl848 datasheet via google. The protocol of these three chips seems very similar, based on my logs of the LiDE 100. You will also want to look at the analog front-end chip which is used (usually Analog Devices or Wolfson Micro), and try to find a manual for that too.
You would then need to get some logs of the windows driver in action, using this tool: http://www.pcausa.com/Utilities/UsbSnoop/ and then you might try to use Pierre's utilities to parse the logs: http://www.pirsoft-dsl-dropzone.de/ Though those utils are made for the 841. allan On Thu, Aug 20, 2009 at 5:21 PM, <mfasolo at ncfsistemi.net> wrote: > Hi, > I Would be glad to write new sane-backend for Canoscan Lide 200. > > Could someone can give me some reference to proceed in SANE's best way > > Thanks > > P.S. > My english could be most horrible than this > > -- > sane-devel mailing list: sane-devel at lists.alioth.debian.org > http://lists.alioth.debian.org/mailman/listinfo/sane-devel > Unsubscribe: Send mail with subject "unsubscribe your_password" > ? ? ? ? ? ?to sane-devel-request at lists.alioth.debian.org > -- "The truth is an offense, but not a sin"
