FAQ

My scanner isn't listed, will the driver work with scanner X?

The simplest way to discover if your scanner is likely to be supported is if you have the Windows 9x driver installed. This places the files E1.ini and Lut.plg under your C:\Windows\ directories. If you perform a search on your Windows C drive for these files then it is likely the driver will work

I have GCC 3.2 on my system and I can't seem to get the driver to wort.

There appears to be an issue with GCC 3.2 that a number of Mandake and RedHat uses have reported. Follow the debug directions below and if you see the following in the debug output then please try rebuilding using a different compiler such as kgcc

[sanei_debug] Setting debug level of dll to 128.
[dll] sane_init: SANE dll backend version 1.0.6 from sane-backends-1.0.9
[dll] add_backend: adding backend `viceo'
[dll] load: searching backend `viceo' in `/usr/localbr/b/sane'
[dll] load: trying to load `/usr/local/lib/sane/libsane-viceo.so.1'
[dll] load: dlopen()ing `/usr/local/lib/sane/libsane-viceo.so.1'
[dll] load: dlopen() failed (/usr/local/lib/sane/libsane-viceo.so.1:
undefined symbol: __gxx_personality_v0)
[dll] sane_exit: exiting
[dll] sane_exit: finished

The driver fails to load what should I do?

First try the following

export SANE_DEBUG_DLL=128
export SANE_DEBUG_VICEO=128
scanimage -L > /tmp/viceo.out

and check the content of the file /tmp/viceo.out. If possible gzip this file and email to to me

I can't get the Windows driver installed, can you help me?

If you are having a problem with the Windows driver then please contact the manufacturer directly. I am developing this driver to work under Linux and other Unix variants that can make use of the Sane scanner framework.

Will your driver work with non-usb based scanners?

In theory yes, at present no. The scanner framework supports E3 and E4 chipsets but the wrapper code currently only supports the USB interface. If someone wants to add parallel support then please feel free to do so.

When I do X the driver crashes or the output is corrupted.

This driver is less than perfect. Especially the E3 chipset support. Please let me know of any problems and if you can find/fix them in the code even better.

Can I contribute changes?

YES.. All help readily welcomed and I can't spend as much time fixing bugs as I'd like to due to other pressures such as working for a living.

How about support for the E5 chipset?

This would be great but I have no docs, sourcefiles, or a scanner to try the code out on. In theory it is an extension of the E4 driver currently included in the project.

Why isn't this project on Sourceforge?

The driver is based on the original Windows driver source code and as such we can't really release it under the GPL or other similar licences at present. Hence Sourceforge won't let us use their facilities.
