But you can test "scanimage -L" the same way: For example what results
export SANE_DEBUG_DLL=4 export SANE_DEBUG_EPSON=128 export SANE_DEBUG_SANEI_USB=128 scanimage -L && echo OK || echo FAILED unset SANE_DEBUG_SANEI_USB unset SANE_DEBUG_EPSON unset SANE_DEBUG_DLL
Thank you for that. Just to make cutting and pasting easier and the output cleaner, I put these command on one line:
# export SANE_DEBUG_DLL=4; export SANE_DEBUG_EPSON=128; \ export SANE_DEBUG_SANEI_USB=128; \ scanimage -L && echo OK || echo FAILED; unset SANE_DEBUG_SANEI_USB; \ unset SANE_DEBUG_EPSON; unset SANE_DEBUG_DLL
Sorry, I made a copy&paste error from my own test. For you it is of course SANE_DEBUG_MICROTEK2 (see the man page for the microtek2 backend) and not SANE_DEBUG_EPSON which I used for my scanner. Therefore do: export SANE_DEBUG_DLL=4 export SANE_DEBUG_MICROTEK2=255 export SANE_DEBUG_SANEI_USB=128 scanimage -L && echo OK || echo FAILED unset SANE_DEBUG_SANEI_USB unset SANE_DEBUG_MICROTEK2 unset SANE_DEBUG_DLL I expect that the microtek2 backend is loaded and executed successfully but you will see only SCSI reledted tests from the backend but no USB stuff which would show you that this backend doesn't do anything regarding USB and therefore your scanner won't work via USB (but via SCSI). Of course you could inspect the sources to be 100% sure but I prefer first of all using user-level tools. Why can't you simply use the SCSI host adapter with which it had worked before? As far as I know some older SCSI host adapters are no longer supported but I am no SCSI expert so that I cannot help you with SCSI questions.
This tells me that scanimage was able to find a dynamic library file corresponding to the "backend" but was (still) not able to find a "device" (I think in this instance a device *file* like /dev/usb/scanner0, yes?).
Exactly. With "export SANE_DEBUG_MICROTEK2=255" you would additionally see the debug output of the microtek2 backend. Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5 Mail: jsmeix@suse.de 90409 Nuernberg, Germany WWW: http://www.suse.de/
