Solved Access right usb controller

[julien40]

Hi,
when I plug in my controller, a /dev/input/event12 is created for example.
With permissions:

crw------- 1 root wheel 0xca Nov 4 22:21 event12

So that I can have the rights to the controller I must do:


# chmod 640 /dev/input/event12

I would like it to happen automatically when I plug it in.
I tried to create a file:

/usr/local/etc/devd/n64gamepad.conf which contains:

#N64 gamepad

notify 100 {        
 match "system" "USB";        
 match "subsystem" "INTERFACE";        
 match "type" "ATTACH";        
 match "vendor" "0x0f0d";        
 match "product" "0x00c1";        
 action "chmod 640 $cdev";
};

But nothing happens, no modification of rights.
Someone would have any idea ?

THANKS.

Did you restart devd(8)? Then unplug and plug the device. The action is only activated when the device is getting attached, i.e. plugged in. If it's still not working show the output of usbconfig with the device plugged in.

yes I restarted "devd" then unplugged and reconnected the controller, still no rights.

The configuration changes the permissions on the corresponding /dev/usb/ device, not the /dev/input/ devices.

You can change those with /etc/devfs.rules:

[localrules=10]
  add path 'input' mode 0755 group operator
  add path 'input/*' mode 0660 group operator

And set the correct rules: sysrc devfs_system_ruleset="localrules"

I personally use the operator group, not wheel for this.

Setting I use for a specific joystick:

% cat /usr/local/etc/devd/dashine.conf
notify 100 {
  match "system"        "USB";
  match "subsystem"     "INTERFACE";
  match "type"          "ATTACH";
  match "vendor"        "0x045e";
  match "product"       "0x028e";
  action "chgrp operator /dev/$cdev; chmod 660 /dev/$cdev";

THANKS for the tip

my user is already in the group wheel for the "su" command to work.

I changed :

/etc/devfs.rules

[localrules=10]
  add path 'input/*' mode 0640

I just need read permission.
No conf file for devd, the controller works.
