udev does not find mouse

[Juanito]

..not totally sure this is a udev problem, but using tc-2.11 with a logitech vx nano mouse:

Code: [Select]

$ cat /proc/bus/input/devices
...
I: Bus=0003 Vendor=046d Product=c526 Version=0111
N: Name="Logitech USB Receiver"
P: Phys=usb-0000:00:1d.0-2/input0
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/input/input5
U: Uniq=
H: Handlers=mouse1 event5
B: EV=17
B: KEY=ffff0000 0 0 0 0 0 0 0 0
B: REL=143
B: MSC=10
..but no corresonding /dev/input/event5 or mouse1 is created:

Code: [Select]

$ ls /dev/input/event*
/dev/input/event0  /dev/input/event1  /dev/input/event2
$ ls /dev/input/m*   
/dev/input/mice    /dev/input/mouse0
..and thus X does not identify the mouse properly

From google

I'm not sure if it's a bug in archlinux udev, but there is no 'by-id' directory and in /dev/udev/rules.d/udev.rules, there is:

Code: [Select]

# by-id links, generic and for the event devices
KERNEL=="mouse*|js*", ENV{ID_SUBSYSTEMS}=="?*", ENV{ID_SERIAL}=="?*", ENV{ID_CLASS}=="?*", SYMLINK+="input/by-id/$env{ID_SUBSYSTEMS}-$env{ID_SERIAL}-$env{ID_CLASS}"
KERNEL=="event*", ENV{ID_SUBSYSTEMS}=="?*", ENV{ID_SERIAL}=="?*", ENV{ID_CLASS}=="?*", SYMLINK+="input/by-id/$env{ID_SUBSYSTEMS}-$env{ID_SERIAL}-event-$env{ID_CLASS}"
if you replace only these 4 ID_SUBSYSTEMS by ID_BUS, it works.

Our udev rules are not written like this, but do we need something similar?

The by-id rules don't matter in this. Anything about it in dmesg? Also, could you give udev logs from plugging it in, and maybe do a quick test on 3.x to see if the newer kernel makes a difference.

from:

Code: [Select]

$ udevadm info --query=all --path=/sys/class/input/event5
P: /devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/input/input7/event5
N: event5
S: char/13:69
E: DEVPATH=/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/input/input7/event5
E: MAJOR=13
E: MINOR=69
E: SUBSYSTEM=input
E: DEVNAME=/dev/event5
E: DEVLINKS=/dev/char/13:69
..seems it's /dev/event5, not /dev/input/event5 - strange it doesn't get put in /dev/input but with "Device" "/dev/event5", the mouse is now found.

No

Also, could you give udev logs from plugging it in

Okay, found it.
