Others have already commented on the fact the USB3 support and the xhci kernel driver may be causing your trouble. > When I first installed this it was fine, everything worked. > > Tonight I tried to scan a document, and xsane can't find the > scanner/printer/etc. > > I removed it with CUPS and reinstalled - no change. > > I removed it and used the Xubuntu printer manager to install it, and > even printed a test page, and that works, and it now shows up in CUPS, > but xsane still can't find the scanner. > > Why does xsane have so much trouble locating what's there and operational? > > How does it manage to forget what used to be there (and still is)? I have had XSane refuse to start on me when I switched devices in the past. XSane keeps a cache with information on devices and settings in the ~/.sane/xsane/ directory. Removing that directory may help. However, when troubleshooting device detection issues, it is better to use the scanimage command-line utility first. See the manual page for usage details but scanimage -L will give the list of detected, usable devices. You can select between these with the -d option. > [snip] Hope this helps, -- Olaf Meeuwissen, LPIC-2 FSF Associate Member since 2004-01-27 Support Free Software Support the Free Software Foundation https://my.fsf.org/donate https://my.fsf.org/join GnuPG key: F84A2DD9/B3C0 2F47 EA19 64F4 9F13 F43E B8A4 A88A F84A 2DD9 -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
