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

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:

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.
