[sane-devel] trying Canon DR-3080C

[D. Hugh Redelmeier]

| From: m. allan noah <kitno455 at gmail.com>

| Looks like the driver cannot write to the operator panel. the dr-20xx
| are the same way. Find the function init_model, and add this block
| after all the other model-specific blocks around line 1202:
| 
| else if (strstr (s->model_name,"DR-3080")){
|   s->can_write_panel = 0;
| }

That fixed it.  Now the device is recognized.

BTW, the gcc warnings generated when compileing canon_dr.c point to
real bugs.  On my machine (AMD64),
	sizeof(size_t) != sizeof(int)
If you use a %d format for a size_t thing, the runtime stdargs logic
will get out of sync.  The simplest fix (assuming that you know that
the value will fit in an int) is to cast the arg to int type.  Even
better would be to use %lu format and cast to unsigned long.

Now the next roadblock.  scanimage fails when trying to actually scan.

sudo doesn't make a difference, but I used it anyway.

Various logsfiles get this:
  Mar  2 16:11:27 redace scanimage: io/hpmud/pp.c 627: unable to read device-id ret=-1
I'm assuming that some hp libsane driver is causing this and that it
doesn't matter.

Here's the scanimage log.  Is it OK to send logs like this to the
mailing list or is it better to use a pastebin?
