[hpoj-devel] hpoj-0.6 kernel module problem

[John L. C. <jl...@cf...>]

Tried the hpoj-0.6 package, and it is a great improvement over
the earlier ones.  However, I have detected a problem with the
kernel modules using modprobe.

Since I wanted to start playing with Sane on my officejet 1170,
I wrote a RedHat hpoj.spec to install the package as it seems
fairly stable.  I decided to install the modules under /lib/modules/misc
so that depmod -a would find it and I could probably change 2.2.x
kernel versions without a recompile.  After running depmod -a,
the modules.dep file, in /lib/modules/`uname -r`, shows the following:

/lib/modules/misc/ieee12844.o:

/lib/modules/misc/ieee12844pp.o:	/lib/modules/misc/ieee12844.o \
	/lib/modules/2.2.15/misc/parport.o

When I run "modprobe -k ieee12844pp", I get:

/lib/modules/misc/ieee12844pp.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
/lib/modules/misc/ieee12844pp.o: insmod ieee12844pp failed

The problem is that modprobe does not know to load paraport_probe.  If
I change the modules.dep file, by hand, to make ieee12844pp depend on
paraport_probe instead of paraport, it works as expected.  Depmod -a
does not detect that ieee12844pp requires paraport_probe.

Attached is a simple hpoj-spec file.  If it is included in the source,
people with redhat can build a package by executing, for example,
"rpm -tb hpoj-0.6.tgz", but it would need to be modified for each
distribution.
