Well scanimage doesn't crashing xorg. In this moment i've
compiled old
sane-backends 1.0.18
and my scaner had return to previous state, it's working for
now, but i
think that this situation is not so fine. Is there anyway
to solve
this problem ?
yes- get a debug log like i asked for previously
allan
when i catch some more time i will try to investigate a
bit more this issue.

oups sorry i had forgotten to add ur email adres to my
previous post
log is here http://atelier1.website.pl/N-A
It is just inf. waiting for light warmup. I just yesterday
found a similar
problem with a newer hardware and will provide a workaround
when done.
Can you test if you can scan successfully if you let the
scanner warm
it's light before you scan with the Avision SANE backend?
Yours,
Well i have left scanner for warmup but this didn't give any
difference.
Regards.
Where is the log to take a look?
Btw. I just noticed in the source I have on the screen the 7400
is marked as AV_LIGHT_CHECK_BOGUS, which essentially ignores the
light warmup state in the code. Can you review if your backend
source you installed from contains this?
Yours,
Hmm
AV_LIGHT_CHECK_BOGUS appears in:
/backend/
767:avision.c
2477:avision.c
107:avision.h
log is here http://atelier1.website.pl/N-A
7400_old.log is previous log
7400.log is new one.
also i'm sure that something had triggered lamp warmup because
after 40min scanner was very hot (much warmer then after 30 scan's
committed with old version of avison).
So, still waiting for the light. Can you add a return
SANE_STATUS_GOODM;
in the beginning of your wait_4_light() function in avision.c?
If I find some time I'll send you some workaround for testing, as
maybe the silicon would report a correct status if polled less often.
If you have free time you could also test upfront if changing the
sleep(1) that should be in your function to sleep(10) or sleep(20)
fixes light detection for your scanner.
Yours,
hmm i need some more info becuse i had
avision.c: In function 'wait_4_light':
avision.c:2439: error: 'SANE_STATUS_GOODM' undeclared (first use in
this function)
i had puted this here:
wait_4_light (Avision_Scanner* s)
{
return SANE_STATUS_GOODM;
Avision_Device* dev = s-hw;
/* read stuff */
struct command_read rcmd;
Regards
Sorry, the trailing M was a typo from my side. SANE_STATUS_GOOD
(taking a 2nd look) it should be.
Depending on your compiler you might have to move the return after
the variable declarations ...
Yours,
Well thats gives difference.
Scanner have moved his head and started initialization.
But then stoped.
new log (7400_1.log) is here http://atelier1.website.pl/N-A
Regards
Hello after while. I would like to ask about this problem, did there is
available any fix for this yet ?

Hi all recently my hp7400c stop working after sane upgrade. i have tested problem on arch linux and ubuntu 8.04 both of them have kernel 2.6.24 and both have recent sane-backends i'm attaching log from scanimage -d avision:libusb:001:002 with set SANE_DEBUG_AVISION=7. Effect is not always the same if i try to scan trough xsane or kooka then i'm getting crash not only of xsane but whole xorg. I will snoop this aspect of problem. If i catch something then i'll send info. if someone have any ideas how to solve problem i will be pleased to hear it. Regards. -- next part -- A non-text attachment was scrubbed...

Ok thx for fast replay. i've uploaded logs here http://atelier1.website.pl/N-A I hope that this issue with xsane kooka is not driver fault (nvidia-96xx here). Regards.
[sane-devel] OpticPro ST24 at cvs-04-01-2001
Hi all i have done small test of ganesys backend (cvs-01042006) with Plustek OpticPro St24.I whose very happy when my scanner start scaning (after uncommenting proper line in genesys.conf).but afther while i discovered that some things are not right. in 150dpi mode (grayscale) everything is perfect :). after change to color i recive bad synchronization between red green and blue. also i'v seen black ?!? im not sure is this right. i know about rgb colors but i dont know about rgb black .reasumming - color palette is wrong(im almost sure that is becuse black apears as another base kolor). in 300dpi mode i have nottice problem with scanning speed which is two times to fast and thats result in leaving physical area of scan(possible damange of scanner).(fix is possible by correct scanning speed. for example normal speed is in 150dpi right now.halfspeed should be in 300dpi.in 600 dpi speed should be 4 times smaller then in 150dpi. and 1200dpi gets 8 times smaller speed).i also think that synchronization of colors is bad by wrong speed of scanning. Scanning in higher resolution is not possible due to leaving of physical scanning area. I hope that those information can be useful. if somebody has more succes with this scanner pleas let me know. ps.sorry for errors in text.english isnt my strong side :) regards BliZZi
