[sane-devel] scanimage -L doesn't work with a supported scanner
Tue, 4 Nov 2003 19:17:01 +0000
I use SANE for the first time.
My scanner (CanoScan N650U) can't be detected by any of the utilities except
sane-find-scanner. It is detected at boot time by the OS (FreeBSD 4.9).
When I set the debug level to 128, this is the output:
(I also tried it as root, that gives the same results)
[sanei_debug] Setting debug level of dll to 128.

I might as well have done something wrong, I went through all documentation I
could find, but I don't have a clue.
The odd thing is, when I try it as a normal user it always finishes quickly,
but as root it took very long time (now it doesn't any more, but I didn't
change the configuration). When I did a "ps ax" at this moment, I saw that
the process was in disk wait state.
