So, uninstall and reinstall libjsw1.5...on which jscalibrator depends
Now, when I run jscalibrator, I get a gui window which says:
"could not access the specified path(s), please verify that the path(s)
are specified correctly and that you have sufficient permission
to access them. Also make sure that the joystick in question is
actually connected, turned on (as needed), not in use by another
program, and that the joystick driver or module is loaded (type
'modprobe <driver_name>'"
The listed device is /dev/js0.

Does this help? As you can see, I've loosened up the perms
on /dev/input/js0 and made it belong to group "users". This
was on someone else's advice. Obviously that didn't help.
I just don't understand how something can be detected in dmesg and
yet there's no I/O address allocated for it.

(PS: Thanks for the tip on modules)

Can you give us the output of modprobe?
Also, what does uname -a say?

How did you try to access joystick? What program?

sd_mod and sr_mod are used for scsi device emulation (cdrw drives for
example). Leave them alone
sunrpc is sun's remote procedure protocol for nfs if you don't want nfs,
you probably don't need these.
Knowing about this is why I recommend anyone who seriously wants to
consider themselves a linux system's administrator to at least install
debian vanilla once (or slackware of lfs). If you don't know why it works
how are you going to ensure that it keeps working?
As for the modules, I usually do:
grep -r module_name /usr/local/src/linux-kernel-source/Documentation
This will point you in the right place and often give you an email message
of the developer if you think found a bug.
Good luck,
Fred Ollinger
