Hello !<br>
<p>
In the last days I tested the last pre0.5 SANE package.<br>
I had to include sys/param.h to get it compiled but then<br>
it worked. Unfortunately I could use preview only in 16bit color mode.<br>
But the appearance of xscan is much better now.<br>
I'm using the following scanners (in different systems):<br>
<p>
MUSTEK MFS-6000CX (label)<br>
Host: scsi1 Channel: 00 Id: 06 Lun: 00<br>
  Vendor: MUSTEK   Model: MFS-06000CX      Rev: 2.71<br>
  Type:   Scanner                          ANSI SCSI revision: 01<br>
<p>
It is connected to an Adaptec 1505 adapter:<br>
<p>
Adaptec 152x SCSI driver; $Revision: 1.7 $<br>
ioports 0x0340 to 0x035f<br>
interrupt 0x0b<br>
disconnection/reconnection disabled<br>
parity checking enabled<br>
synchronous transfers disabled<br>
0 commands currently queued<br>
enabled debugging options:<br>
<p>
queue status:<br>
no not yet issued commands<br>
no current command<br>
no disconnected commands<br>
<p>
waiting: SCSISEQ (); SCSISIG (DATA OUT); INTSTAT (lo); SSTAT (BUSFREE PHASECHG<br>
); SSTAT (); SXFRCTL0 (CH1 ); SIGNAL (); SELID (01), SSTAT2 (SEMPTY ); SFCNT<br>
(0);<br>
 SCSICNT (0), OFFCNT(0), SSTAT4 (); DMACNTRL0 (16BIT PIO READ INTEN ); DMASTAT<br>
(DFIFOEMP )<br>
<p>
enabled interrupts ()<br>
<p>
(this is from /proc/scsi)<br>
This is what you wanted to know<br>
<p>
[mustek] attach: firmware revision 2.71<br>
[mustek] attach: found Mustek scanner model MFS-06000CX (flatbed scanner)<br>
<p>
The following problems occured:<br>
<p>
It is a 3-pass scanner: with SANE only grayscale scanning works. On color<br>
scanning I get the error message : "device busy". This maybe an adapter timeout<br>
problem as it is discribed for the ncr810 adapter but I have another MUSTEK<br>
scanner program from Arno Augustin : Email:<br>
 aoaugust@informatik.uni-erlangen.de ; with<br>
this program I can scan even color images (no error messages). Maybe you can<br>
have a look at it. Further more the scanner drives to far if the range is set<br>
to 14inches. This sounds really bad. Thanks to god it did't destroyed the<br>
scanner.<br>
I could fix it by setting the maximum resolution to 300 dpi in mustek.c because<br>
this the optical resolution of the MFS-6000CX.<br>
Now it scan grayscale images without errors but with maximum resolution<br>
(299dpi)<br>
I can`t get the whole selected area (it is cut off)<br>
<p>
I also installed SANE (sane-pre0.5) to work with an HP SCANJET 4P.<br>
Unfortunately I had no time yet to provide the necessary firmware data to you.<br>
(I have only time-limited access to this device.) It is on the same SCSI-BUS as<br>
the system harddrive and a zipdrive.<br>
But there were really no errors! The only problem was to make SANE recognize<br>
the HP as a sane device. HP scanners have unusual device type (from scsi.h):<br>
#define TYPE_PROCESSOR      0x03    /* HP scanners use this */<br>
I changed this to TYPE_SCANNER and it worked.<br>
Maybe the resolution setting could be more sensitive (the highest possible<br>
resolution is 1599 dpi - the step size is to big).<br>
<p>
SANE version 0.5:<br>
<p>
It compiles without errors. When invoked I get the message: "cannot locate<br>
symbol strndup".<br>
configure states the following:<br>
checking for strdup... (cached) yes<br>
checking for strndup... (cached) no<br>
<p>
Thats all for today...<br>
<p>
Thank you for programming such an important project.<br>
