Canoscan 4400F driver - update
by Andreas Robinson
::
Rate this Message:
Hi folks,
I've been busy working on a driver for the Canoscan 4400F for a good while and thought it best to come out with an update in case someone wonders whether I dropped off the planet. Yesterday, I received some unexpected help from Wim Brul, (Thanks again!) and was finally able to get the damned contraption to send images properly! The attached image should give you an idea how far along it is. (Or isn't.) Basically, I have a good grasp of how the scanner works, but there's still a lot of work to be done on the actual driver. The curious can visit http://github.com/andr345/gl843driver where I'm dumping my code at irregular intervals. (The interesting files are gl843_*.c) It is a standalone test driver, where I've experimented with accessing the scanner registers by name, instead of by I/O address and bit number. It's *very* convenient, but so different from the current Genesys driver that I'm doubting whether it can ever be merged with it. Anyhow, back to work! If you have questions or opinions, I'll be happy to answer them.

Hi,
@allan: I do not run xsane on the same mashine like the sane-server, so I do not understand how to write the log you want me to. "xsane... 2>net.log" sanimage on the mashine where the sane-server runs, works fine. @Olaf:"Compile the backend with gcc -Wall -Werror should give a cluebat." What is meant by that? I'm using the optware package, so it is not compiled on my router. I am maintainer of the package, so I can patch it to be compiled in a different way, but how?

The easiest way to know would be for you to install a real OS on your machine (i.e. Linux, perhaps in a VM), and make sure that you can scan over the network. allan > > Regards > Oliver > > > > > -----Ursprüngliche Nachricht----- > Von: m. allan noah [mailto:kitno455@...] > Gesendet: Dienstag, 20.
