I have made all of the recommended changes to the patch and created a web page for the HP3500 backend at http://projects.troy.rollo.name/rt-scanners/ - the updated patch is available from that page.
The updated hp3500.desc file is attached. -------------- next part -------------- ; SANE Backend specification file ; ; It's basically emacs-lisp --- so ";" indicates comment to end of line. ; All syntactic elements are keyword tokens, followed by a string or ; keyword argument, as specified. ; ; ":backend" *must* be specified. ; All other information is optional (but what good is the file without it?). ; :backend "hp3500" ; name of backend :version "1.0" ; version of backend :manpage "sane-hp3500" ; name of manpage (if it exists) :url "http://projects.troy.rollo.name/rt-scanners/"; ; backend's web page :comment "HP3500 series scanners." :devicetype :scanner ; start of a list of devices.... ; other types: :stillcam, :vidcam, ; :meta, :api :mfg "Hewlett-Packard" ; name a manufacturer :url "http://www.hp.com"; :model "ScanJet 3500C" ; name models for above-specified mfg. :interface "USB" ; interface type of the device: ; "SCSI", "USB", "Parport (EPP)", ; "Parport (SPP)", "Parport (ECP)", ; "Serial port" or "Propretiary". :status :good :model "ScanJet 3530C" ; name models for above-specified mfg. :interface "USB" ; interface type of the device: :status :good :model "ScanJet 3570C" ; name models for above-specified mfg. :interface "USB" ; interface type of the device: :status :good ; :comment and :url specifiers are optional after :mfg, :model, :desc, ; and at the top-level.
