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

[Ryan Harkin]

Hi,
I have a Umax 1220P parallel port scanner that I have sucessfully install=
ed=20
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 som=
eone=20
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 c=
an=20
only get it to work using directio (port 0x378) and not when I use ppdev=20
(port /dev/parport0).

I have spoken to Henning a couple of times on IRC (as "omnium") and he wa=
s=20
very helpful in getting my SuSE 7.2 setup working.  However, he advised m=
e to=20
post to the list with this latest problem.  I have copied "stefdev" too,=20
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 p=
atch=20
from sourceforge (note: I get exactly the same results with 1.0.9-pre1):

Then the process hangs indefinitely.  OK, so to get some debug, I install=
 SANE=20
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=3D255 scanimage -L
  [sanei_debug] Setting debug level of umax_pp to 255.

  [umax_pp] unused arg: local_only =3D 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=20
/dev/parport0" and re-run scanimage with no luck:

  # SANE_DEBUG_UMAX_PP=3D255 scanimage -L

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

=2E.. 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.
