[Solved] udev won't trig my simple rule (jscal gamepad calibration)

monsieur moche · 2015-06-09 17:08:26

Hello,

I want the system to automatically calibrate my gamepad whenever I plug it in. As adviced in the Wiki (https://wiki.archlinux.org/index.php/Ga … alibration), I've written a udev rule:

florian@flobox:~$ cat /etc/udev/rules.d/85-jscal.rules 
SUBSYSTEM=="input", ATTRS{idVendor}=="045e", ATTRS{idProduct}=="028e", ATTRS{serial}=="1E6674E", ACTION=="add", RUN+="jscal -s 8,1,0,-5000,4500,19423,19078,1,0,-5500,128,19781,16513,1,0,127,127,4227201,4227201,1,0,-4000,5500,18745,19781,1,0,-3000,3000,18113,18113,1,0,127,127,4227201,4227201,1,0,0,0,536854528,536854528,1,0,0,0,536854528,536854528 /dev/input/by-id/usb-©Microsoft_Corporation_Controller_1E6674E-joystick"

It seems udev doesn't run the jscal command as my gamepad isn't calibrated when I plug in it.

The attributes seem correct though:

florian@flobox:~$ udevadm info --attribute-walk --name /dev/input/by-id/usb-©Microsoft_Corporation_Controller_1E6674E-joystick

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I must be missing something basic. I've even tried and removed all the attributes, but it didn't help.

What did I do wrong?

You didn't follow the rules.

OK! I've prefixed jscal with /usr/bin and now it works perfectly. Thank you very much!
