I'm running under Centos 7 (kernel 3.10.0-862.14.4.e17x86_64) and the version of SANE I downloaded from the Centos repository via yum install. When I run sane-find-scanner -v -v it tells me "found USB scanner (vendor=0x0a9 [Canon], product= 0x220e [CanoScan] at libusb:001:002", but, after checking several possibilities, says: <Couldn't determine the type of USB chip (result from sane-backends 1.0.24)>. Running scanimage -L tells me "No scanners were identified.....". I've seen documentation that the N1024 has complete support via the plustek backend, and uses the LM9883 ASIC (which is not one of the ones sane-find-scanner says it checks for). I've tried modifying the /etc/sane.d/dll.conf file by commented out everything except net, plustek, and canon_dr, modified the /etc/sane.d/plustek.conf to try several different methods of referring to the scanner (currently using:
[usb] [usb] 0x0429 0x220e device libusb:001:002 and modified /etc/sane/canon_dr.conf by commenting out everything and adding to the end: #CanoScan N24OU option vendor-name CANON option model-name CanoScan option version-number N24OU usb 0x04a9 0x220e I'm pretty much out of ideas. Any and all suggestions gratefully received
