[sane-devel] Question on old Mustek Scanner (12000SP)

Sun, 29 May 2005 21:29:13 +0200

Dear listmembers,
I use a Mustek Scanner (since years) but now decided to upgrade my system f=
rom=20
SuSE 8.1 to (in the meantime) SuSE9.3)
I had had the scanner connected to the same SCSI-bus as the harddisk and th=
e=20
cdrom and the zip-drive, but in the meantime this became impossible.
So I added a second SCSI card (decided for the scanner and the zip drive) a=
nd=20
(in general) things work ok.
What does *not* work is start scans after a long sleep of the scanner:

=46rom then on I can scan 100 scans without further issues. Seems to me as =
if=20
somehow some timeouts became shorter than before? I use SuSE9.3 with kernel=
=20
2.6.11.4-20a-smp. Should those messages really bother me? However, they=20
do :-). I did not see similar issues with kernel 2.4.21 on the same scanner=
=20
and the same scsi-card using the same harddisk etc. Something must have=20
turned significantly faster than before.

Many thanks for any inputs,
take care
