The SCSI-II standard about scanners is sufficiently vague that you<br>
|
||
|
cannot build a scanner solely on the specs. <br>
|
||
|
<p>
|
||
|
I mean that a disk drive implements a well-defined "read" and "write",<br>
|
||
|
and that's sufficient for a functional disk drive. The amount of<br>
|
||
|
commands that a scanner needs to support to be able to function is<br>
|
||
|
much larger, but the specs leave enough "vague" that a manufacturer<br>
|
||
|
almost always needs to do essential stuff in "vendor extentions".<br>
|
||
|
<p>
|
||
|
Tamarack sent me their interpretation of the SCSI-II specs. I was able<br>
|
||
|
to build the Tamarack backend on that. Getting access to the SCSI-II<br>
|
||
|
specs and noting the similarity, I wasn't able to get the coolscan to<br>
|
||
|
work with the tamarack driver. (I didn't put in very much time though).<br>
|
||
|
<p>
|
||
|
A general SCSI-II standard driver would need:<br>
|
||
|
<p>
|
||
|
- A "standard" way to approach a scanner, adhering to SCSI-II/scanner<br>
|
||
|
as close as possible.<br>
|
||
|
<p>
|
||
|
- A config file that specifies at what points this scanner is<br>
|
||
|
"different"from the standard: Specifying extra required commands at<br>
|
||
|
certain points, and ways to extract information like "bytes per<br>
|
||
|
line" from the replies.<br>
|
||
|
<p>
|
||
|
It is not a trivial task to create such a backend. <br>
