findkeyboards - no device node found

findkeyboards - no device node found

[John Serock]

I could use some help troubleshooting findkeyboards. It is not finding
my keyboard. I'm not sure if the issue is in the findkeyboards script
or if it is something else. Once the findkeyboards script failed, I
tried manually running the udevadm commands it uses. Here is what I am
seeing:

/lib/udev$ udevadm info --version
173

/lib/udev$ ./findkeyboards
AT keyboard: no device node found

/lib/udev$ echo $?
5

/lib/udev$ udevadm trigger --dry-run --verbose
--property-match=ID_INPUT_KEYBOARD=1
/sys/devices/platform/i8042/serio0/input/input4
/sys/devices/platform/i8042/serio0/input/input4/event4

/lib/udev$ udevadm info --query=name
--path=/sys/devices/platform/i8042/serio0/input/input4/
no device node found

/lib/udev$ udevadm info --query=name
--path=/sys/devices/platform/i8042/serio0/input/input4/event4/
input/event4

It looks like the findkeyboards script can't find the device node for
the first (input4) device, which causes the script to exit with status
5 before it checks the second (event4) device. I'm not sure whether
the input4 device should have a device node or not. Any
troubleshooting help would be appreciated.

Thanks.

What a weird coincidence, I also used findkeyboards again this morning
because I got a PM for a keymap fix, and noticed the very same
problem. I'm not sure when this got broken, or whether it's due to a
kernel or udev change, but this fixes it:

Thanks,

Martin
