Canoscan N650U made obsolete by LL3.4?

[Peejay]

[member=2]Jerry[/member] I found when I did the 'sudo apt' you suggested I had indeed not installed the whole package - I'd omitted  the dbg and dev files believing they were not likely to affect day-to-day operations. Anyway I opted to install them but unfortunately it's made no difference to the availability of the scanner to the system.
I took a copy of the terminal dialogue and attach it to this post.

I did indeed have the scanner working with LL3.2. I was quite surprised because I've never had any joy with it on Ubuntu though several years ago Linux Mint did connect with it (no later than LM13 I don't think). In recent times my only source of joy with it prior to LL3.2 has been MX14 and 15, which is Debian based. In MX16, which I haven't yet installed they have changed from SimpleScan to Scan2pdf and on the Live version at least that operated the scanner.

Prior to LinuxLite I was trying PeppermintOS but it didn't really suit me whereas LinuxLite sits very well with the way I like to work. So I was really pleased to find LL3.2 also operated the scanner - and now just as disappointed that 3.4 seems to have gone the way of other Ubuntu-based distros so far as my scanner is concerned.

Throughout though it's never been clear why operation should be problematic because it's clearly supported by SANE and everyone appears to include the full SANE system in their distros. The scanner itself does still work - MX14  still doing its stuff.

I'm beginning to wonder whether whether some recent kernel changes might have affected the detection system, but that's just a guess because although I'm quite an experienced user I'm no techie. Perhaps the terminal dialogue will offer some clues to someone better qualified than I to assess it.

Thank you once again for your trouble. And just in case I have given a contrary opinion through this mishap with the scanner, may i say how impressed I am with the way Linux Lite is put together and the attention you give to practical working for ordinary users like myself. I think it's quietly exceptional in that regard.
