Thank you for your advice, unfortunately I cant get epkowa to detect my scanner, even when specifying  
"usb 0x04b8 0x0129 #Epson 10000XL" in epkowa.conf (values coming from lsusb)
 
I get the following run:
> SANE_DEBUG_DLL=127 SANE_DEBUG_EPKOWA=127 scanimage -L
 [sanei_debug] Setting debug level of dll to 127.
 [dll] sane_init: SANE dll backend version 1.0.12 from sane-backends 1.0.21
 [dll] sane_init/read_dlld: processing /usr/local/etc/sane.d/dll.d ...
 [dll] sane_init/read_dlld: done.
 [dll] sane_init/read_config: reading dll.conf
 [dll] add_backend: adding backend `epkowa'
 [dll] sane_get_devices
 [dll] load: searching backend `epkowa' in `/usr/local/lib/sane'
 [dll] load: trying to load `/usr/local/lib/sane/libsane-epkowa.so.1'
 [dll] load: dlopen()ing `/usr/local/lib/sane/libsane-epkowa.so.1'
 [dll] init: initializing backend `epkowa'
 [dll] init: backend `epkowa' is version 1.0.212

 No scanners were identified. If you were expecting something different,
 check that the scanner is plugged in, turned on and detected by the
 sane-find-scanner tool (if appropriate). Please read the documentation
 which came with this software (README, FAQ, manpages).
 [dll] sane_exit: exiting
 [dll] sane_exit: calling backend `epkowa's exit function
 [dll] sane_exit: finished
 
So my scanner isn't detected (and it is when i comment epkowa in dll.conf and uncomment epson2).
By the way, SANE_DEBUG_EPKOWA doesnt seem to be effective, even if epkowa is loaded (although SANE_DEBUG_EPSON2 works, so maybe libepkowa was build without debug support).
I couldnt find where to download the latest epkowa release you were speaking about, is it in the git repo? Currently I have sane-backends 1.0.21 which seems to me to be the latest available binary) and I'm using the epkowa library "libsane-epkowa.so.1.0.15".
 
I also tried directly :
sudo scanimage -d epkowa
scanimage: open of device epkowa failed: Access to resource has been denied

So not working either, is there another way to check if epkowa supports this particular device ?

thank you, this might improve its life expectation ^^

Well, don't know yet :)

Hope too, and thank you again for your time
