New to forum and problem with udev, hal_input and
I am Rolf from Germany and just joined this forum.
Today i switched from Ubuntu 8.04 to 10.04.
Generally it works, but my jogwheel don't.
It is an jogwheel with AVR and HIDKeys, working fine under 8.04.
But now, under 10.04 i get "No input devices could be opened. This usually indicates a misconfigured system..."
Then i tried to call from a shell with
halrun
loadusr -W hal_input -KRAL SAITEK
show pin
No luck as normal user, same error.
But, when i am root, the shell command above works, and i see the pins.
So i logged in to ubuntu as root. Axis starts without errors annd my jogwheel works!
So i think, the error must have do do with permissons.
But it's wrong to work permanently as root, isnt it?
In the /etc/udev/rules.d i have a file with SUBSYSTEM="input", mode="0660", group="plugdev"
And the normal user belongs to the group plugdev.
What may be my mistake? Where to look for errors or wrong configuration?
Best regards from Germany!

What version of EMC are you using?

on the 'External Controls page' there is an option USB joystick. It will help you write a rule and test it.
You will need your joystick handy.
after that just quit PNCconf. The rule will be written on you system.

if you are using EMC newer then 2.4.3 then you could use pncconf to help you make a rule.

thanks for your quick answer. I made an fresh install, updated the system. With the new, fresh and clear system i tried pncconf.
2 rules where added do /etc/udev/rules.d, owned by root.
But when i try do test the device with pncconf:
requested devicename = obdev.at HIDKeys
No input devices could be opened. This usually indicates a misconfigured
system. Please read the section 'PERMISSIONS AND UDEV' in the hal_input
manpage
Then i tried sudo pncconf. With that, i can test the device, show pins and so on.
What may be wrong? It is really an fresh install (10.04), i have only applied the updates.
Best regards, Rolf

i tested some things. My jogwheel acts as an HID device.
So i tested to set the permission under /dev/input with chmod 0666 *
And: IT WORKS!
So the only questionss are:
- which device is my wheel exactly? (I think, lsusb is my friend)
- how to change the permission for this device?
Maybe udev rules, i don't know. I am not a very good linux user.
Perhaps someone can show me the right way?
