[sane-devel] Problems with mustek_pp and releasing the parallel port

Eddy,

I am running libieee1284-0.2.8-0.pm.0

As root I stopped inetd, and executed the above commands.  The first time
I did this I got the contents of first.txt.

So I rebooted the server and tried again but didn't appear to get any
output from scanimage (I didn't use > /dev/null but > test.pnm which
didn't appear to grow at all).

So I ran SANE_DEBUG_MUSTEK_PP=128 SANE_DEBUG_SANEI_PA4S2=255 saned -d128
and scanimage -d net:localhost:mustek_pp:Mustek-1200CP -T but there
appeared to be no output from the scanimage -T.

So I then ran saned -d128 and scanimage -d
net:localhost:mustek_pp:Mustek-1200CP and got the output found in the
attachment sanedonly.txt

I then tried again with the original commands you requested but, in the
end I lost my courage because it didn't appear to be doing anything still
so I stopped.

Finally I tried ANE_DEBUG_MUSTEK_PP=128 SANE_DEBUG_SANEI_PA4S2=255
scanimage -d mustek_pp:Mustek-1200CP > test.pnm but again there is was no
file generated so I decided to stop the output for fear of breaking my
scanner.

Hope this helps.

Jim
