[Wylug-help] Scanner Detection / Device Names

[Dave Fisher]

Hi Folks,

Sorry for the number of posts recently, but this is one of those weeks when I
force myself to do all the configuration stuff that I've been putting off for
months.

Currently, I'm struggling to setup a scanner, which is 'officially' flagged as
'unsupported' by sane, but is probably nothing more than a rebadged version of
a scanner that is known to work.

sudo sane-find-scanner identifies the device itself:

  found USB scanner (vendor=0x07b3, product=0x045f [600dpi USB Scanner], chip=GT-6816?) at libusb:003:004

sudo lsusb produces all the detail I've pasted after my sig.

The next step in most howtos or manpages is simply to run scanimage -L

Of course this doesn't work, because it doesn't know which backend to use, and
I can't tell it which one to use, because:

  1. I'm not 100% sure which backend to use, although I suspect it's either the
      plustek one or the gt68xx one.  
  2. I don't know the /dev/* name to use, because that requires the backend

This mailing list message deals with exactly the model I have (Iriscan 2):  
  
  http://lists.alioth.debian.org/pipermail/sane-devel/2008-February/020933.html

But I'm not sure how to use the info contained within it.

I assume that the patch mentioned has not yet found its way into Ubuntu
packages, and I don't understand sane well enough to be able to reproduce the
patch process myself.

I've tried, and failed, to simply hack the relevant details into /etc/sane.d/gt68xx.conf 

Any thoughts?

Dave
