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;

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.

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...

[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
