Execute a udev rule AFTER another rule

Hello,

I have the same problem as the one described here https://bbs.archlinux.org/viewtopic.php?id=150114: My usb mouse is disconnected when i stopped using it for a few seconds.

The solution is to disable auto suspend for this device using the following command :

sudo bash -c "echo on > /sys/bus/usb/devices/1-3.1/power/control"

I tried to automate this operation by creating a new udev rule. I created the following file /usr/lib/udev/rules.d/43-mouse-local.rules (I kown, i should create this file in the /etc/udev/rules.d/ folder but it just for test :-) )

ACTION=="add", SUBSYSTEMS=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c018", TEST=="power/control", ATTR{power/control}="on"

This rule match the correct event/device (I made some debug) BUT it is not executed in the right order.

My udevd log are :

ATTR '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3.1/power/control' writing 'on' /usr/lib/udev/rules.d/43-mouse-local.rules:2

The first line

ATTR '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3.1/power/control' writing 'on' /usr/lib/udev/rules.d/43-mouse-local.rules:2

shows that my rule is executed and the power/control attribute is set to "on". And the last line

ATTR '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3.1/1-3.1:1.0/../power/control' writing 'auto' /usr/lib/udev/rules.d/42-usb-hid-pm.rules:34

shows that another rule has erased my modification.

The documentation says "All rules files are collectively sorted and processed in lexical order" my rule name is 43-mouse-local.rules and the other rule name is 42-usb-hid-pm.rules so i don't understand why my rule is no executed after the 42-usb-hid-pm.rules.

Thanks in advance

Re: Execute a udev rule AFTER another rule

Why have you changed your rule to use "SUBSYTEMS" instead of "SUBSYSTEM"? They have different meanings.

See original autosuspend thread.

Re: Execute a udev rule AFTER another rule

Hi,

Thank you for your help. I fully followed your advices .

I comment my 43-mouse-local.rules file.
I created the /etc/udev/rules.d/91-local.rules file with the following content :

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c018", ATTR{power/control}="on"

The only difference with your configuration described in https://bbs.archlinux.org/viewtopic.php … 0#p1178070 is that i replaced

ATTR{product}=="Razer Abyssus"

by

ATTR{idVendor}=="046d", ATTR{idProduct}=="c018"

I still have the same problem :
