[sane-devel] Does the Canon Lide 80 work?

[goland55 at aol.com]

I made the changes you suggested and troubleshot a few things and got 
the scanner to be found as a LiDE 60 with scanimage.  I got an invalid 
argument error when I tried to do 'scanimage >image.pnm'.

Below is a debugging log after I issued 'export 
SANE_DEBUG_GENESYS_GL841=255' and 'export SANE_DEBUG_SANEI_USB=255'.

I'm not sure if this is a problem with the backend not supporting my 
scanner or if I have made a mistake in the setup of the scanner.  Any 
help would be appreciated.

  Hi,

It doesn't work yet.

As none of the genesys developers seems to own such a scanner, it's up
to you to add it to the backend. See the ongoing discussions on this
list about the genesys backend.

As a quick'n'dirty trst. you could get the source code of
sane-backends (1.0.17 at least) and change the code of
backend/genesys_devices.c (at the end):

Change

  {0x04a9, 0x221c, &canon_lide_60_model},

to

  {0x04a9, 0x2214, &canon_lide_60_model},


and also add

usb 0x04a9 0x2214

to genesys.conf.

Bye,
  Henning
