Hi Erik,
I retired using your recommendation and it doesn't help much. Looks
like the SANEI_DEBUG_SANEI_SCSI doesn't produces much output, but I do
see some low level in /var/log/message ( I did a tail -f
/var/log/message before I start sane):
Apr 5 13:23:49 localhost kernel: __alloc_pages: 3-order allocation failed.
Apr 5 13:23:49 localhost kernel: __alloc_pages: 2-order allocation failed.
Last message repeat many times
I don't know if this have anything to do with sane.
Here is the environment:
SANEI_DEBUG_SANEI_SCSI=255
SANE_DEBUG_MICROTEK2=255
SANE_DEFAULT_DEVICE=/dev/sg5
SANE_SG_BUFFERSIZE=32768
Here is the debug output again:
====================================================================
[sanei_debug] Setting debug level of microtek2 to 255.
