Agfa F40 vs OSX ! No scanner found !

Postby LSI_Support » Thu Nov 27, 2003 10:44 am

Agfa f40 will NOT work with SilverFast on OSX when the manufacturer scan software is installed.

You have to delete a kernel extensions to work with SilverFast:

location of the extension:

the Extension filename is AgfaScannerFireWire.kext This file is protected. Please use the terminal window to open it.


sudo rm -rf <space>

then drag?n?drop the extension into the terminal window and press <enter>.

After a reboot the scanner works fine.

The filename of the Agfa firewire kernel extension installed by FotoLook might also be "AgfaFireWireSBP2Scanner.kext".

Where to find the "Terminal" application?
You will find the terminal within /Applications/Utilities/.


Code: Select all

ls /system/library/extensions
you will see if an "Agfa(whatever).kext" is present in your system blocking SilverFast's access to your Agfa scanner.
Please note the sorting: alphabetical, capital lettes first, so "APPLE" is listed above "Agfa".

Code: Select all

sudo rm -rf /system/library/extensions/Agfa*
will let you get rid off the kernel extension, letting you use SilverFast again (reboot is necessary).
You will need the system administrator's password (if set) to remove the kernel extension.

However, you will not be able to use FotoLook software afterwards, as it needs the Kernel extension for scanner access.
But provided with the FotoLook tools there is a helper app which does install the kernel extension with a simple double-click, so it can easily be restored.

BTW, the command

Code: Select all

kextstat | grep -v apple
shows all loaded kernel extensions that were not provided by Apple (with the Mac OS X).
The '|' character is entered by holding the option (or: alt) key and pressing the '7' key.

since my query about Agfa F40 + OSX + 10.5.5 FireWire has not been "approved", and given the link to THIS topic as a solution, it is obvious that no one has read and understood the original message:
again: agfa F40, silverfast Demo, NO AGFA SOFTWARE INSTALLED, NO AGFA FIREWIRE KERNEL-EXTENSION. the scanner shows in the system profiler, the works using USB, the scanner DOES NOT WORK ans ist NOT RECOGNIZED when connected using firewire.

i really would like to buy silverfast but not if it just doesn't work with firewire (and NO - there is NO "AgfaFireWireSBP2Scanner.kext" in my system, because there has no agfa software ever been installed (well, ok, years ago running OS 9.22)

thanks for any help or ideas

Dear HDT,

The FireWire connection is not supported under Leopard for your scanner model, please check the description of the scanner and it supported features on our site at:

Thanks for your interest in our products
