Hi Britt,<br>
|
||
<p>
|
||
up to here the SCSI communication was ok. Now the large amounts of data<br>
|
||
will be transfered. Several possibilities for failure:<br>
|
||
<p>
|
||
Termination ok ?<br>
|
||
hp-backend in SANE V1.0 has some problems in it. If possible try<br>
|
||
upgrading to SANE 1.01 ?<br>
|
||
<p>
|
||
To localize the problem, you also can increase the value of<br>
|
||
SANE_DEBUG_HP and SANE_DEBUG_SANEI_SCSI.<br>

||
