Great, now we have the exact source of the problem at least :)
I'm wondering if that code is actually right (with or without patch)..
Not sure what LCD_COMMAND_ATTENTION is intended to do? And shouldn't
LCD_COMMAND_4_BIT be written with NIBBLE_CTRL?
Anyone on the list who uses these/wrote the original code?
CC'd Der Tiger referenced in the commits, if he still has the same
email.. Might have some insights; is it working for him?

Update; i've copied module/owlib/src/c/ow_2408.c file from the 2.8p15 sources

It is working now....
Great pinpointing! I suspect the following change:

Patch from Der Tiger for LCD screen buttons
Nico, can you try the following:
1. restore the 3.1 version of the file
2. Apply the above patch, in reverse.
If you are using a git checkout, you can do 'git revert -n 85dd96'
If you are using the 3.1p1 tarball, look at the above URL, and find the
code lines added (+). Replace those with the lines removed (-).
3. Rebuild
If this does not help, please include expected vs actual behavior.
Paul is maintainer of the code?, i've not knowledge how to debug this further.
I'd say the main one, but there are others as well. Unfortunately he has
been unseen lately.
Thanks,
Nico

Hi Johan,
I've setup nieuw beaglebone system, if i use the version 2.8 included in de
debian 7 repo the display works, the version 3.1 from the git don't. I'm using
now a DS9097U/ds2409 as interface, but no difference
There was a bunch of changes in the ds2409 (hub) handling between those
versions. Could you test without the ds2409?
owwrite /1F.177102000000/aux/29.09C211000000/LCD_H/clear 1
owwrite /1F.177102000000/aux/29.09C211000000/LCD_H/screen aap
Is neither working (control nor writing)? I'm not entierly familiar with
the LCD interface of the DS2408, so a "expected" and "actual"
description would be helpful :)
But do test without the hub first, to rule that out.
The debug what you asked for:

Perfect!
