[sane-devel] Umax 1220P not detected with /dev/parport0

[Ryan Harkin]

Hi,
I have a Umax 1220P parallel port scanner that I have sucessfully installed 
with SuSE 7.2 to use /dev/parport0 as both root and normal user.

Now I am trying to get it to work with a newer distro and wondered if someone 
could help out.  And I realise that you all have work to do on 1.0.9!

I have tried SuSE 8.0, Mandrake 9.0 and now RedHat 8.0.  In all cases I can 
only get it to work using directio (port 0x378) and not when I use ppdev 
(port /dev/parport0).

I have spoken to Henning a couple of times on IRC (as "omnium") and he was 
very helpful in getting my SuSE 7.2 setup working.  However, he advised me to 
post to the list with this latest problem.  I have copied "stefdev" too, 
though I guess he subscribes to this list!

Here's what I've done so far.

I've made sure that the parport_pc and ppdev modules are installed:

  # /sbin/modprobe parport_pc
  # /sbin/modprobe ppdev

Then I have built the 1.0.8 backend, patched with the latest Umax 1220P patch 
from sourceforge (note: I get exactly the same results with 1.0.9-pre1):

  $ tar -zxvf ~/sane-backends-1.0.8.tar.gz  &> ~ryan/doc/untar-backends.txt
  $ zcat ~ryan/umax1220p-2.16.gz | patch -p1 &> ~ryan/doc/patch-backends.txt
  $ ./configure --enable-parport-directio &> ~ryan/doc/configure-backends.txt
  $ make &> ~ryan/doc/make-backends.txt
  $ su

Then the process hangs indefinitely.  OK, so to get some debug, I install SANE 
and test using scanimage:

  # make install &> ~ryan/doc/makeinstall-backends.txt
  # ldconfig
  # vi /usr/local/etc/sane.d/dll.conf
  [I remove the # from #umax_pp]

  # SANE_DEBUG_UMAX_PP=255 scanimage -L
  [sanei_debug] Setting debug level of umax_pp to 255.

  [umax_pp] unused arg: local_only = 0
  device `umax_pp:0x378' is a UMAX Astra 1220P flatbed scanner
  [umax_pp] sane_exit: (...)

So now I modify /usr/local/etc/sane.d/umax_pp.conf to change the port to "port 
/dev/parport0" and re-run scanimage with no luck:

  # SANE_DEBUG_UMAX_PP=255 scanimage -L
  [sanei_debug] Setting debug level of umax_pp to 255.

  (umax_pp_low.c:4757)  <-- ln 4588 with 1.0.9-pre1

... and then it hangs.

Does anyone have any idea of where I would start to solve this problem?

Help is very much appreciated.

Thanks for your time and sorry for sending such a long email.

Ryan.
