Hi, Can you run scangui with sane debug enabled? if you are using epson2 backend: SANE_DEBUG_EPSON2=16 scangui or epkowa backend: SANE_DEBUG_EPKOWA=16 scangui OK, I ran LC_ALL=C SANE_DEBUG_EPKOWA=16 scangui but it doesn't make a difference. Nothing printed to stdout/stderr. Or should I find a logfile somewhere? Created attachment 72784 [details]

Log of xsane with SANE_DEBUG_EPKOWA=INFO
OK, got it. Debug level is not numerical for epkowa. I've attached log of the non-working scangui command and, for comparison, the one of a working xsane invocation. Both created with SANE_DEBUG_EPKOWA=INFO. Oops accidentally changed resolution OK thanks, Can you increase the log level? Can you try with Skanlite and give the sane device name as parameter? skanlite -d epkowa:<something...> I don't know the format epkowa uses for WLAN models. "scanimage -L" should give you the name. I think this is a backend bug, but it would be good to know what triggers it. /Kåre % scanimage -L device `epkowa:net:drucker.altum.de' is a Epson Stylus NX635/SX535WD/Stylus Office BX535WD flatbed scanner skanlite w/o any parameter shows the same behaviour. Using it with "-d epkowa:net:drucker.altum.de" works fine. I'll attach a log with SANE_DEBUG_EPKOWA=HEX. Created attachment 72792 [details]

Unfortunately I have no idea what is wrong :( My guess is that the backend has some problem with the timing of the probing of devices and the opening of the device... I have sent a mail about it to the sane mailinglist /Kåre |
