Be very careful with USB scanners. They not only have to
|
|
<BR>
|
|
be supported by the USB sub system (which as far as I remember
|
|
<BR>
|
|
was a problem with the USB drivers from SuSE 6.3), in
|
|
<BR>
|
|
addion to this SANE has to provide support for the particular
|
|
<BR>
|
|
scanner as well.
|
|
<BR>
|
|
<P>There are two things that can go wrong: The scanner manufacturer
|
|
<BR>
|
|
does not provide information about how the device uses the USB
|
|
<BR>
|
|
bus. This means that the USB kernel driver can not be modified
|
|
<BR>
|
|
so that the scanner in question can be recognized.
|
|
<BR>
|
|
<P>The other problem is that the scanner manufacturer has to
|
|
<BR>
|
|
provide information about the command set the scanner uses.
|
|
<BR>
|
|
<P>I can only speak for EPSON scanners, so if you need information
|
|
<BR>
|
|
about any other scanners, please check the "Supported Scanners"
|
|
<BR>
|
|
page at www.mostang.com/sane and click on the links in the
|
|
<BR>
|
|
table.
|
|
<BR>
|
|
<P>As far as EPSON is concerned: They have published both parts.
|
|
<BR>
|
|
I know how to talk to the scanner via USB and I also know
|
|
<BR>
|
|
which commands the scanners understand. At this time the
|
|
<BR>
|
|
Perfection 636U, 1200U, 1200Photo and 610 are supported.
|
|
<BR>
|
|
<P>If you are considering an EPSON scanner, I think you should
|
|
<BR>
|
|
go with the USB version. They are cheaper and you find them
|
|
<BR>
|
|
pretty much everywhere.
|
|
<BR>
|
|
<P>I mentioned that the SuSE version you are using does not
|
|
<BR>
|
|
have support for USB scanners. If you can compile a kernel
|
|
<BR>
|
|
it is no big problem to get the latest version of the USB
|
|
<BR>
|
|
subsystem and do it yourself. If you think you need some
|
|
<BR>
|
|
assistence, please send me a private email (You would not
|
|
<BR>
|
|
be the first one whom I walk through the kernel build
|
|
<BR>
|
|
process via email).

<P><EM>> Hi everyone
|

</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Am trying desperately to come to terms with SANE, kernels and
|
|
</EM><BR>
|
|
modules. As I
|
|
<BR>
|
|
<EM>> see it I have the choice between a SCSI scanner and a USB one for
|
|
</EM><BR>
|
|
Linux.
|
|
<BR>
|
|
<EM>> The latter seem freely available whilst the former have to be
|
|
</EM><BR>
|
|
ordered
|
|
<BR>
|
|
<EM>> through a specialist dealer (here in Spain at least). Does SANE
|
|
</EM><BR>
|
|
recognise
|
|
<BR>
|
|
<EM>> both in the same way or is the way that they are set up different?
|
|
</EM><BR>
|
|
<EM>> Apparently, my kernel (SuSE 6.3 from the box) has support for USB
|
|
</EM><BR>
|
|
<EM>> backported from the 2.3 kernel. Does this mean that I can plug in a
|
|
</EM><BR>
|
|
<EM>> supported USB scanner and have SANE recognise it as a device?
|
|
</EM><BR>
|
|
<EM>>
|

</EM><BR>
|
|
<EM>> Any help however small much appreciated.
