I didn't mean a package from wheezy-backports, I meant a package from jessie's main. I assume you want to stay on Debian' stable release, so echo 'APT:Default-Release "stable";' >> /etc/apt/apt.conf if you haven't done so already. Next echo 'deb http://http.debian.net/debian jessie main' >> /etc/apt/sources.list and apt-get update apt-get install libsane=1.0.24 should get you there, in principle. All commands should be run with root privileges, and, no, I haven't tested this. > Third: it is difficult for me to believe that there is > no way for a variant of a very well-known firm, Canon, > to have its particular modus operandi identified. > I would hope that the information given by sane-find-scanner: > > found USB scanner (vendor=0x04a9 [Canon Inc], product=0x2774 > [MF4700 Series]) at libusb:001:004 > > would be sufficient to add the support for this particular > Canon all-in-one to my present libsane. As Allan has already stated in a separate message, it takes a lot more than just that and, fortunately for you, that has been done already. > I should add: running scanimage --version yiels: > scanimage (sane-backends) 1.0.22; backend version 1.0.22 The latest version is 1.0.24. > I reiterate my call for help!
