Hi,
<BR>
<P>I'm trying to use an Epson Perfection 1640SU on an HP-UX 10.20 system
<BR>
with sane-backends-1.0.4 and sane_epson_20010522, latest HP-UX SCSI
<BR>
cumulative patch. Unfortunately, I don't get very far, and I would be
<BR>
grateful for any help.
<BR>
<P>find-scanner says:
<BR>
<P>find-scanner: found processor &quot;EPSON Perfection1640 1.04&quot; at device /dev/scanner
<BR>
<P>However, scanimage --help -d epson:/dev/scanner takes a very long time
<BR>
and eventually fails, leaving the scanner in an error state (LED
<BR>
blinking red). The behavior is not fully consistent: Sometimes the
<BR>
scanner doesn't change to the error state, sometimes I even get the
<BR>
listing of device options, and sometimes the scanner is not even
<BR>
recognized at all. Here is a typical debug output:
<BR>
<P>[...]
<BR>
<P>[epson] sane_open(/dev/scanner)
<BR>

<BR>

<BR>
[epson] receive buf, expected = 4, got = 0
<BR>
[epson] ident failed
<BR>
scanimage: open of device epson:/dev/scanner failed: Invalid argument
<BR>
<P>[...]
<BR>
<P>It would be very helpful to know where to look: Is the problem with
<BR>
the HP-UX code of SANE, or in the Epson backend, or maybe somewhere
<BR>
else again?
<BR>
<P>Thanks in advance
<BR>
<P><PRE>
