The main problem is, that Linux is a broth, spoiled by too many cooks:
The kernel module interface changes with every minor release depending
on the mood of one of those developers. Every other of those many
GNU/Linux components changes too quickly. Hardware vendors can't keep up
making drivers for those many versions and distributions and they don't
want to spend most of their development effort for this only because one
of a thousand customers wants to run their product on that special
flavour of Linux.
The Elo touchscreen works wit SUSE 9.3 and kernel 2.6.11.4-20a-smp. I
tried to use SUSE 9.0 with kernel 2.4 but that does not even run on the
hardware with SATA controllers and with Suse 9.1 the whole USB stuff is
unuseable. When trying to get it working with SLES9 SP3 and kernel
2.6.5-7.244-smp it does not work:
- Elo driver module for Suse 9.3 (kernel 2.6.11.4-20a-smp)
does not load with error message "Invalid module format"
- Elo driver module for Suse 9.1 (kernel 2.6.4-52-smp)
causes the whole system to freeze.
- Elo does not have a binary module for SLES9 SP3
I know it's not Novells fault. You only grab the stuff built by some
thousand people, compile and configures them and put them together. It's
impossible to verify everything. If something works with Linux version X
it mostly does not work with Linux version X-1 or X+1. Some years ago
when Linux was new, I was a fan. But now I start to hate it due to that
huge inconsistency. :-(
Bye
Bernd
