UDEV – Getting an Old Scanner to Behave..

Adventures With Linux ™ Posted on by

I recently acquired a vintage (2006?) Minolta Elite 5400 II scanner, and – according to the VueScan support info, I needed to ”set up libusb device protections”..   That info included a link to a somewhat ancient SANE USB support page – last changed in 2003!..

Fedora – Getting Rid of Unwanted ‘virtbr0’

Adventures With Linux ™ Posted on by

I did a clean install of Fedora 23 on my new ‘built from recycled components‘ crash-and-burn test system recently, and all went reasonably well – apart from – apparently – having to re-partition an already-partitioned drive (!)… After booting for the first time, I found that a ‘bridged’ network link – virtbr0 – was active..    As I … Continue reading →

Fedora – Installing a Working ZoneMinder..

Adventures With Linux ™ Posted on by

Installed ZoneMinder ( https://zoneminder.com ) for some IP and WiFi cameras, and the first thing to remember is to not use the Fedora version!    This is due to the lack of ffmpeg and vlc support in that version, which makes the software somewhat less than useful.. Fortunately, there is good Fedora support, with a fully-functional version – … Continue reading →
