Could well be a bug in the NetBSD version of the SANE scsi routines<br>
|
|
(in sanei/sanei_scsi.c). I don't think they have been tested all that<br>
|
|
well (or is anyone else using SANE under NetBSD at present?).<br>
|
|
<p>
|
|
Julian> PS. Where can I get documentation on the scanner SCSI<br>
|
|
Julian> command set? I tried searching HP's web pages, but didn't<br>
|
|
Julian> find anything.<br>
