+ Following verbatim https://help.ubuntu.com/community/SaneDaemonTutorial previously worked in Trusty with my HP OfficeJet 5610v All-in-one plugged into a USB 2.0 port, where the Trusty server had a wireless interface setup as a WAP for clients to connect directly to. However, it now no longer works in Trusty when instead ethernet through a switch or via WiFi router, and doesn't work in Utopic or Vivid. For example, in Windows 8.1 with SaneTwain 1.3.6, it used to work. Now it pops up a window:
  Error
  No devices found on backend.
  
  However, in the Device drop down it notes:
  hpaio:/usb/Officejet_5600_series?serial=XXXXXXXXXXXXXX
  
  Ubuntu 15.04 client with either xsane or simple-scan doesn't find anything. Running the following from a terminal results in either a crash or no SANE devices found as per https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1442960 :

  *** Error in `scanimage': double free or corruption (!prev): 0x00007f5a939fff10 ***
  
  The scanner works fine locally on the server via simple-scan and xsane.
  
  Intermediary device networking being the root cause has been ruled out
  as I connected the server and client via ethernet through a switch,
  disabled wireless and still reproducible. Confirmed clients and host may
  ping each other.
  
  Tried disabling ipv6 on just and both server and clients, no change.
