<i>&gt; </i><br>
<i>&gt; Just wanted to follow up on this... I recently changed my SCSI card</i><br>
<i>&gt; from the Adaptec 2940UW to a dual-channel Symbios 786 chipset. When I</i><br>
<i>&gt; started up SANE with your driver, I managed to scan line art drawings</i><br>
<i>&gt; okay, but Gray16 scans led to a stream of SCSI error messages on the</i><br>
<i>&gt; console, ultimately hanging with a message saying the scanner wasn't</i><br>
<i>&gt; releasing the SCSI bus.</i><br>
<i>&gt; </i><br>
<i>&gt; This may be that the Symbios is simply less tolerant of ancient</i><br>
<i>&gt; hardware, or may be bugs in your driver or in SANE itself...</i><br>
<i>&gt; </i><br>

Ouaou! Imagine that. Now I know what the command RELEASE is for. Sadly I<br>
don't know how to use it. I suppose you have more than one device in the<br>
SCSI don't you? Unfortunately I have only one so I can't really test the<br>
possible race conditions... <br>
<p>
I would very much appreciate if your comments were redirected to the<br>
SANE mailing list so we can get some feedback.<br>
<p>
SANE mailing list is not a heavy one (about 15 mails per day) but you<br>
don't have to subscribe. If you send mails to<br>
<p>
<a href="mailto:sane-devel@mostang.com">sane-devel@mostang.com</a><br>
<p>
and you don't forget to put on Cc: yourself you hopefully you get all<br>
the interesting answers.<br>
<p>
Currently there is another person who tried to use the backend but<br>
unfortunately he has a OneScanner (256 shades of Gray). I hope that I<br>
will be able to help both of you with one development effort after july<br>
8.<br>
<p>
About the documentation issue I haven't decided yet. I think the best<br>
thing is to write it by myself since I am the author (and the one to<br>
blame). However I would be more than happy if you could possibly revised<br>
it since my english are not so much polished.<br>
<p>
Also I posted this mail reply to the SANE list in order to get some<br>
feedback. I hope it is allright with you. So let's go public.<br>
<p>
<p>
Dear SANE developers/advanced users<br>
<p>
-Should a backend release a SCSI bus? and when?<br>
<p>
-What's is the "official" Sane backend documentation format? Man Page?<br>
<p>
<p>
Milon<br>
<p>
PS<br>
I HOPE I haven't screwed everything with the mail replies and forward<br>
addresses. In case I did I am sorry...<br>
