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>

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>

Cool! Did you find the specs from your own or by the URL stated at the<br>
|
|||
|
|
man page?<br>

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>

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->0.74 I add a lot of support (mainly options) for the other<br>
|
|||
|
|
models (OneScanner, ColorOneScanner).<br>
