|
<P>Tim and I have been looking at this offline. The significance
|
|
<BR>
|
|
of lk 2.3.43 was the addition of a new sg driver that has an
|
|
<BR>
|
|
additional interface. Recent versions of SANE use that newer
|
|
<BR>
|
|
sg interface. The problem that Tim reported seemed to be caused
|
|
<BR>
|
|
by timeouts ** resulting in scsi bus resets. Anyway the problem
|
|
<BR>
|
|
seems to disappear with the recently released SANE 1.0.4 .
|
|
<BR>
|
|
[The original report was based on SANE 1.0.3 and earlier.]
|
|
<BR>
|
|
<P>There is also a problem report with the SnapScan 1236 <--> aha152x
|
|
<BR>
|
|
combination also based on SANE 1.0.3 . This one is looking
|
|
<BR>
|
|
like an "uninitialized errno" bug fixed in SANE 1.0.4 .
|
|
<BR>
|
|
<P>** SANE's newer sg interface shortens the per command timeout
|
|
<BR>
|
|
from 10 minutes to 10 seconds. Most other OSes have a timeout
|
|
<BR>
|
|
value of 1 minute or more. I suspect 10 seconds may be too short.
