Now that I have said that. ASPI is a direct link to SCSI devices from
|
||
|
|
windows programs. ASPI just forwards the SCSI commands that programs send
|
||
|
|
to it to the SCSI bus.
|
||
|
|
|
||
|
|
If you use the wrong scsi device in your setup file, you can send
|
||
|
|
completely bogus commands to the wrong device - An example would be
|
||
|
|
formatting your hard drives (assuming the device gave you permission -
|
||
|
|
if you're running as root, all bets are off).

Cookbook for setting up scanner: (At least how mine is to work)
|
||
|
|
================================
|
||
|
|
|
||
|
|
Windows requirements:
|
||
|
|
=====================
|
||
|
|
0) The scanner software needs to use the "Adaptec" compatible drivers
|
||
|
|
(ASPI). At least with Mustek, they allow you the choice of using
|
||
|
|
the builtin card or the "Adaptec (AHA)" compatible drivers. This will not
|
||
|
|
work any other way.
|
||
|
|
|
||
|
|
1) You probably need a real windows install of the software to set the
|
||
|
|
LUN's/SCSI id's up correctly. I'm not exactly sure.
|
||
|
|
|
||
|
|
LINUX requirements:
|
||
|
|
============================================================
|
||
|
|
0) Your scsi card must be supported under linux. This will not work with
|
||
|
|
an unknown scsi card.
|
||
|
|
|
||
|
|
1) Compile generic scsi drivers into your kernel.
|
||
|
|
|
||
|
|
2) Linux by default uses smaller scsi buffers than Windows. There is a
|
||
|
|
kernel build define SG_BIG_BUFF (in sg.h) that is by default set too low.
|
||
|
|
The SANE project recommends 130560 and this seems to work just fine. This
|
||
|
|
does require a kernel rebuild.
|
||
|
|
|
||
|
|
3) Make the devices for the scanner (generic scsi devices) - look at the scsi
|
||
|
|
programming how-to for device numbering.
|
||
|
|
|
||
|
|
4) I would recommend making the scanner device writable by a group.
|
||
|
|
I made a group called "scanner" and added myself to it. Running as root
|
||
|
|
increases your risk of sending bad scsi commands to the wrong device. With
|
||
|
|
a regular user, you are better protected.
|
||
|
|
|
||
|
|
5) Add a scsi device entry for your particular scanner to wine.conf.
|
||
|
|
The format is [scsi cCtTdD] where C=controller, T=target, D=LUN
|
||
|
|
|
||
|
|
ex. I set mine up as controller 0, Target 6, LUN 0.
|
||
|
|
[scsi c0t6d0]
|
||
|
|
Device=/dev/sgi
|
||
|
|
|
||
|
|
Yours will vary with your particular SCSI setup.

General Information:
|
||
|
|
====================
|
||
|
|
The mustek scanner I have was shipped with a package "ipplus". This
|
||
|
|
program uses the TWAIN driver specification to access scanners.
|
||
|
|
|
||
|
|
(TWAIN MANAGER)
|
||
|
|
ipplus.exe <---> (TWAIN INTERFACE) <---> (TWAIN DATA SOURCE . ASPI) -> WINASPI
|
||
|
|
|
||
|
|
NOTES/BUGS:
|
||
|
|
===========
|
||
|
|
The biggest is that it only works under linux at the moment.
|
||
|
|
The ASPI code was only tested using a Mustek 800SP with a Buslogic
|
||
|
|
controller under Linux.
|
||
|
|
|
||
|
|
I make no warranty to the aspi code. It makes my scanner work. Your scanner
|
||
|
|
may explode. I have no way of determining this. I take zero responsibility!
