<i>&gt; Hello, all.</i><br>
<i>&gt; </i><br>
<i>&gt; I recently came into an Apple Color OneScanner for $20 at the local</i><br>
<i>&gt; surplus store. To my joy, there was a backend for it in the SANE package.</i><br>
<i>&gt; However, I noticed the driver has not been worked on for some time and its</i><br>
<i>&gt; most recent developer only had an Apple Scanner to work with.</i><br>
<p>
The one and only developer I should say... though there are 4 to 5<br>
potential user which they had expressed interest. I hope you downloaded<br>
the sane-0.74 since the apple backend has greatly reworked from the<br>
sane-0.73 package.<br>
<p>
<i>&gt; </i><br>
<i>&gt; I have been experimenting with the backend and found (and subsequently</i><br>
<i>&gt; corrected) a logic flaw which did not flush the buffer after the scan had</i><br>
<i>&gt; completed. The scanner says it wasn't in a blocked condition, yet there</i><br>
<i>&gt; was data still in its buffer waiting to be transferred to the host</i><br>
<i>&gt; computer. I added a check for still-available data failing the check for</i><br>
<i>&gt; a blocked condition as another condition to transfer data from the</i><br>
<i>&gt; scanner. I can provide a patch for this (it only affects one line of</i><br>
<i>&gt; code).</i><br>
<i>&gt; </i><br>
I am open to suggestions. You are invited to send/post anything you<br>
have. I am afraid I didn't excacltry understand what are you describing<br>
which is OK because if I understood it I would have fixed it.<br>
<p>
<i>&gt; In the meantime, I have since obtained and printed Apple's programming</i><br>
<i>&gt; specs for these scanners. They have helped enormously thus far in</i><br>
<i>&gt; tracking this particular bug down.</i><br>
<p>
Cool! Did you find the specs from your own or by the URL stated at the<br>
man page?<br>
<p>
<i>&gt; </i><br>
<i>&gt; Has anyone been hacking this backend lately? Judging by the traffic on</i><br>
<i>&gt; the list in past months, apparently not much has been said about it in</i><br>
<i>&gt; recent times (at least in the Subject: lines).</i><br>
<i>&gt; </i><br>
<p>
Well as I said there are 4-5 users.<br>
<p>
I with an applescanner (Everything works for me ofcourse)<br>
<p>
One with an applescanner also. He has problems which are dependant with<br>
his SCSI controller. He has two controllers and he tested it. But after<br>
all it may be related with the bug you are describing.<br>
<p>
Two with one OneScanner. The one helped me with some debugging (no<br>
results), but the other asked for the Documentation and he said that he<br>
will try to fix something. That happened the past week.<br>
<p>
Finally there was one guy that he claimed that he had quick/hacked a<br>
program to scan from ColorOneScanners. I asked him if it was possible to<br>
built some of his knoweledge in the SANE backend. He said that he had no<br>
time for such a task, but he could send me the code. I said OK, fine<br>
thanks. Well I saw that code as much as did. I think that was<br>
<p>
<i>&gt; If any of the people who have worked on this backend are on this list, I</i><br>
<i>&gt; would certainly like to hear from you, especially the poor soul who has</i><br>
<i>&gt; the Apple Scanner, but not either OneScanner (I got one now, I'll be your</i><br>
<i>&gt; guinea pig. :) ).</i><br>
<i>&gt; </i><br>
<p>
The apple backend was based on mustek backend of the sane-0.69. I change<br>
all mustek to apple by a sed script and start coding. I suppose that<br>
make the only active developer of the apple backend. In the<br>
sane-0.73-&gt;0.74 I add a lot of support (mainly options) for the other<br>
models (OneScanner, ColorOneScanner).<br>
<p>
<i>&gt; There are some other glitches, but right now, getting that last bit of</i><br>
<i>&gt; data out of the scanner was my priority before I could go on to Bigger and</i><br>
<i>&gt; Better Things(R).</i><br>
<i>&gt; </i><br>
<i>&gt; I look forward to hearing from you! :)</i><br>
<i>&gt; </i><br>
<i>&gt; --Ian.</i><br>
<i>&gt; </i><br>
<p>
Sure there are glitches. I am open to suggestions.<br>
