I have previously sent in the output of: export SANE_DEBUG_PLUSTEK=19 ; scanimage -L
as advised by Gerhard Jaeger and want to add some observations. I am able to use the scanner on the same hardware, using a Slax Linux LiveCD and sane-backends-1.0.17 Back to OpenBSD, what I have also noticed, is that if I disconnect the scanner, then reconnect it, scanimage -L will show the scanner as being connected, but only for a limited length of time. It is not long enough to do anything useful though. If I disconnect it then reconnect it and try xscanimage, I will get the initial dialogue box and can select resolution and color depth, but when I attempt scan something, the scanner has become unavailable again and I get a pure black scan. I'm only able to get even this far, if I do all this as root, but that is obviously a permission issue and I can address that after I have got this working. Hope the above helps and I have again included the sane debug output below. -- Best regards, Craig http://slashboot.org/ Support OpenBSD http://www.openbsd.org/orders.html # export SANE_DEBUG_PLUSTEK=19 ; scanimage -L [sanei_debug] Setting debug level of plustek to 19.
