lomoco udev rule not working

[Bismark]

Binary package hint: lomoco

When a mouse supported by lomoco (listed in /etc/udev/lomoco.rules) is detected it is suppose to run /lib/udev/udev.lomoco using the settings in /etc/default/lomoco.

My mouse is listed in lomoco.rules but when I unplug and plug it back in the rule does not fire.

I have to manually run lomoco to get it to set the resolution on my mouse properly.

I can confirm this bug both on Gutsy and Hardy with Logitech MX510.
I've edited /etc/default/lomoco to use 800cp resolution (LOGITECH_MOUSE_RESOLUTION=800) but it is not set during startup.
There is possible workaround - see http://ubuntuforums.org/showthread.php?t=219894 - section 3 (add init.d rule to set up resolution on boot), but this won't set the resolution on hotplugging and resuming from suspend/hibernation.

[Kjell Braden (afflux)]

Confirmed. This is because of:

1.) /etc/udev/rules.d/025-lomoco.rules is named incorrectly, should be only two digits.
2.) /etc/udev/lomoco.rules seems to check for the wrong subsystem: changing to usb_endpoint fixed it for me.

will check wether it affects debian too.

[Darren Warner (launchpad-dazwin)]

Confirmed in intrepid beta 1 using a Logitech MX310

I worked around it by commenting out the SUBSYSTEM != "usb_device" line at the top of /etc/udev/lomoco.rules

A few other points:

- According to /etc/udev/rules.d/README, files in this directory should not be symlinks.
- The README seems to indicate that the rule should be run at 80, not 25 (I'm certainly no udev expert though).

[Sergei (msergei)]

I can confirm this bug in K/Ubuntu 8.10.

These two steps made it to work again for me.

1. Running
cp /etc/udev/lomoco.rules lomoco.rules /etc/udev/rules.d/80-lomoco.rules
2. Editing to usb_device to usb_endpoint

This must be fixed as an update to 8.04 and 8.10!!!

Hi:

I also stumbled across this problem, but I fixed it in a slightly different way: I changed the "SUBSYSTEM != usb_device" to "ATTR{name} == Logitech USB-PS/2 Optical Mouse". How did you people know to change it to usb_endpoint? Using udevinfo, I get "SUBSYSTEM == input". I'm pretty confident I'm looking at the right entry because the ATTR{name} match works, and it is unique to that entry. Any help appreciated.

Cheers,
UbuntuCleric

I confirm this bug with package 1.0beta1+1.0-5 (up-to-date 8.10) and that the suggested workaround from Sergei works.
Any chances to get this applied?

[Jan Vlnas (jnv)]

In Ubuntu 9.04 rules file was correctly moved to /lib/udev/rules.d/40-lomoco.rules
But the problem still remains, my MX510 mouse resolution is not set on the system startup (with edited settings in /etc/default/lomoco). As far as I have tested, it seems that udev.lomoco script doesn't get executed. Therefore I think that bug exitsts in 40-lomoco.rules file.

This happens on freshly installed Ubuntu Jaunty, package lomoco from universe: 1.0beta1+1.0-5ubuntu1.

Shall I reopen this bug, report new one or is it only my problem?

[Jan Vlnas (jnv)]

Previously mentioned fix with "usb_endpoint" is a solution to this bug.
I've attached a patch which directly changes /lib/udev/rules.d/40-lomoco.rules file.

The rule actually causes lomoco to run twice when the device is connected, but it's still better than nothing.

I guess there is one more problem with udev rule, see bug #382229 I have just reported.

[robled (robled)]

I'm curious as to how you guys even have any udev entries for lomoco. I've just installed it on 9.04, but when I search the /etc directory for lomoco all I get is the defaut config file:

#find /etc -name lomoco
/etc/default/lomoco

[Jan Vlnas (jnv)]

NTolerance, lomoco rules are placed in /lib/udev/rules.d/ - although you are right it shouldn't be that way. Package supplied rules should go to the /etc/udev/rules.d/. This is yet another (although minor) bug in lomoco package.

[Cybjit (cybjit)]

I did not get the any of the fixes to work in karmic. I had to make changes to both
/lib/udev/udev.lomoco
/lib/udev/rules.d/40-lomoco.rules
to make it work.

[Cybjit (cybjit)]

Here is a patch against the package build instead.

[B. Clausius (barcc)]

Here is a debdiff based on Cybjit's patch.
If someone wants to test it, look in my ppa:

[Søren Holm (sgh)]

Confirmed ..... The attached files works great for me. Please push the changes into karmic.
