Sadly no. I've tried it with and without the hyphen.
I've tried many such things. I've checked for case sensitivity, I've
tried different line orderings, etc. etc.
I think the plustek.conf file isn't at fault here I'm afraid.
Anyway, I notice that on the page for the Plustek drivers, the UT12 is
down as working, which means (I assume) that someone has reported to you
that it works. From memory this might be Michael Häckel
####@####.####
Could whoever did get a Plustek UT12 working (if anyone) email me their
sane.d/plustek.conf, and /etc/modules.conf files? and anything else they
think would be useful? On or off list...
It looks to me like the sane_init function of the driver is returning
without doing anything... (ie. not even the DBG() macro calls in the
source code actually return anything to STDOUT when debugging is turned
on). I think the "return attach("/dev/pt_drv",0);" line might somehow be
getting called wrongly and hence returning the wrong result... or
something like that anyway.
I even tried a complete rebuild just now from source without involving
RPM spec files or anything, and that also failed to work.
Thanks.
Yours,
Kev.
PS. Some debugging...
Firstly, the sane-internal debugging stuff...
[sanei_debug] Setting debug level of dll to 256.
[dll] sane_init: SANE dll backend version 1.0.4 from sane-backends-1.0.6
[dll] add_backend: adding backend net
[dll] add_backend: adding backend plustek
[dll] load: loading backend plustek
[dll] load: dlopen()ing `/usr/lib/sane/libsane-plustek.so.1'
[dll] init: initializing backend `plustek'
[dll] init: backend `plustek' is version 1.0.0
scanimage: open of device plustek:/dev/usbscanner failed: Invalid
argument
[dll] sane_exit: exiting
[dll] sane_exit: calling backend `plustek's exit function
Here's an strace of the scanimage pointed to the /dev/usb/scanner0
device. It's a similar story if I use /dev/usbscanner as well (both
devices have the same major and minor numbers). It seems to show the
backend just opening up the config file, freeing its data structures
(munmap) and then exiting, without doing anything.
