Do check your usb rules (udev? systemd ? ) or where ever they are defined; for how it is defined on the usb buss often changes (generic antedote,I know but the usb buss can be instantiated in several different ways (on linux) and I'm not sure on the latest (moving) semantics). On a side note, I'm buying a John Deere 4000 (low hours, well maintained), from my brother in law, so any private emails on advice are most welcome. I'm going to use it to push dirt around for a house flipper team effort; and when I get angry at 'puters... ;-) James

Hello Dale, I always keep old (very old) backups of the config file in /etc/cups to see if when a software upgrade occurs, or I have to use the admin page of cups to update/modify/test print/scanner hardware. So it's an easy check therein, if you kept old copies in /etc/cups. Sometimes newer versions of cups do not work well with older or obscure features of various printers/scanners. As far as USB goes, the device's device driver could have been change or it, as a legacy (usb) device became a new part of one of the unified device drivers. You'll have to research that or build a new/test kernel with all sorts of USB drivers enabled. You definately have a usb issue, at the very least. If those (2) ideas do not bear fruit, find a usb sniffer and use that. You might have to go to a windows box to test the scanner too. Not likely, but the usb chip could have went bad http://vusb-analyzer.sourceforge.net/ http://sourceforge.net/projects/usbsnoop/ or general usb tools (may) help: app-admin/usbview sys-apps/usbmon sys-apps/usbutils etc.. many more usb sniffer too. Just eliminate the possibilities. I'd test it on a windows box if necessary too. This all begs the question of how it was set up : (after the usb issue is resolved). hplip, cups, *sane*, ??? hth, James

Hi Dale, the scanner part of my Brother DCP stopped suddenly also one month ago. My troubles were caused by the upgrade from sane-backends-1.0.23 to 1.0.24-r1. Downgrading immediately led to a working scanner again. [snip] Cheers, Jörg

This all begs the question of how it was set up : (after the usb issue is resolved). hplip, cups, *sane*, ??? hth, James I did use sane to set it up. Well, I installed the sane package and to be honest, it just sort of worked without me doing anything that I recall. I might add, I now have a USB mouse, try finding a PS/2 mouse at short notice. The scanner is plugged into the port right next to it right now. I did however try other ports that I know work because I can use USB sticks in them. So, it's either some broken upgrade of something or as much as I hate to say it, my scanner needs to be buried. For some reason, I didn't even try hplip for scanning. It never occurred to me. I have xsane and Skanlite installed and use those. They say it can't find the scanner. I figure until it shows up on the lsusb list, nothing is going to work regardless of what front end I use. I didn't get a chance to today but tomorrow I plan to go to my brother's and plug the scanner into his computer. He uses Kubuntu. If the scanner works there, then it is something to do with my rig. If it don't show up on lsusb there either, I need to go buy a shovel and find a comfy spot in the back 40. :-( Thanks. I'll post when I get to test some more.

Heck, if it works, I don't care what version the package is. LOL It's not like it is going to have new features. ;-) Thanks for the info. Dale :-) :-) -- I am only responsible for what I said ...
