[sane-devel] backends-1.0.14 scsi epson
Sat, 1 May 2004 18:36:54 +0200
I have an EPSON-1640 with an ADF.
Since I use linux-2.6 which still has trouble with USB I was
forced to use the SCSI-Interface of the scanner.
The last sane-backends version that the scanner works with
is still 1.0.12.
I looked into the code of sane-backends-1.0.14 last day and tried
to find out why it not worked with my scanner _and_ the ADF.
I found that it works again if I comment out in feed()/epson.c
if (SANE_STATUS_GOOD != (status = expect_ack (s)))
and instead add simple
expect_ack here always returns 9.
Starting with backend-1.0.13 the sanei_scsi layer has changed
and therefore I assume a bug in the scsi status handling, because
expect_ack() has not changed since sane-backends-1.0.12.
Maybe one of the sanei_scsi developers can help here ?
