Hello Spiro,

I never touched that setting, and indeed you are right: /bin/sh points
to the 'dash' shell. By the way, I want to clarify that I usually use a
gnome-terminal, which runs a bash shell and not a dash one.

Hmm, now I believe to be the guilty one: I recofigured the dash package
dpkg-reconfigure dash
and when it asked me if i want to set it as the default one (it also
says that it is "smaller and faster than bash"... so maybe I been caught
in this trap long time ago when I installed dash!). Now i answered 'No',
and so the bash shell is the default one.
With the /bin/sh pointing to bash, I got a fresh checkout of the branch
called v0_4_0_bugfix_branch, and followed successfully all the steps in
"3.1.2. Compilation". Then I followed the steps in the section
"3.1.3. Loading the module", and I got an error only with the last
command, i.e.:
luca@c65:~/opencbm/cbm4win2/cbm4linux$ sudo /sbin/insmod cbm lp=0
insmod: can't read 'cbm': No such file or directory
I searched for that file this way:
luca@c65:~/opencbm/cbm4win2/cbm4linux$ sudo find / -iname "cbm.ko" -exec
ls -la {} +
-rw-r--r-- 1 luca luca 15820 2007-11-03 18:25

the two ones in /lib/modules/2.6.20/misc/cbm.ko and
/home/luca/opencbm/cbm4win/sys/linux/cbm.ko has been prolly copied along
with the last compilation, but I am nore sure about the first one. Do
you have an idea of when those files are created? And why my error?
Notice that to load the module i had to go into sys/linux directory and
insmod'ed the cbm.ko from there.

Yeah, I use udev.

Yes, it is.

Well, the file gets copied in there, so i wonder why it does not work. I
tryed also to /etc/init.d/udev restart with no luck.
I could provide some useful info here below to track down the error.
luca@c65:~/opencbm/cbm4win2/cbm4linux/sys/linux$ ll /dev/cbm
crw-rw-r-- 1 root users 10, 177 2007-11-03 19:45 /dev/cbm
luca@c65:~/opencbm/cbm4win2/cbm4linux/sys/linux$ id
uid=1000(luca) gid=1000(luca)
groups=20(dialout),24(cdrom),25(floppy),29(audio),30(dip),44(video),1000(luca),1002(vboxusers)
So, i added my accout "luca" to the group user, and then i run 'newgrp
users', now i my account is able to use /dev/cbm device. Not sure it is
a sensible way to fix the error though.
Besides, /var/log/syslog, when i call insmode, reports the following
"debug" log output, maybe could help understanding the error:
