I am running Gentoo using udev to manage devices. My computer is a
generic IBM compatible computer using an ATX type motherboard with a
PS/2 mouse attached to a port on the motherboard.

lsmod reveals:

psmouse 14920 0

However, I do not appear to have any mouse device listed in /dev

ls /dev/psaux
ls: cannot access /dev/psaux: No such file or directory

ls /dev/mouse
ls: cannot access /dev/mouse: No such file or directory

ls /dev/input/mice
ls: cannot access /dev/input/mice: No such file or directory

Have I forgotten to configure something?

Mark.

As /udev/ has already been on the block for a couple of years, I'd doubt
that it would be a goof-up by the Gentoo developers in the /udev/ scripts -
it cannot be excluded as a possibility, but I deem it unlikely - so a few
other things need to be looked at first. ;-)

The most obvious question would be whether you have /sysfs/ mounted on
*/sys.* Normally, the answer would be yes, since */dev,* /sysfs/
and /procfs/ are mounted by the /init/ scripts in Gentoo - I believe I got
this information from Art Hagen. ;-)

The next thing to check is your kernel configuration. I'm not sure exactly
where in the configuration the pertaining options are to be found, but you
should double-check your Input/Output sections and Human Input Devices
(HID).

There is also an option there to create a */dev/psaux* character device, and
my guess is that you've forgotten to say "Y" there.

Just my 2 Eurocents, but that should be better than if they were US
Dollarcents at this moment in time.

On my system, /etc/X11/xorg.conf's pointer section uses /dev/psaux
/dev/psaux is a link to /dev/misc/psaux

which isn't on your system..... looking further:
( man -k udev ... play around with udevinfo ... )
$ udevinfo --query=name --name=/dev/misc/psaux --attribute-walk

Udevinfo 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.

looking at device '/class/misc/psaux':
KERNEL=="psaux"
SUBSYSTEM=="misc"
DRIVER==""
ATTR{dev}=="10:1"

No driver; looks like it's built into the kernel.

<become root>
# cd /usr/src/linux
# make menuconfig
# /psaux <-- foward slash in menuconfig to search

Symbol: INPUT_MOUSEDEV_PSAUX [=y] ?
? Prompt: Provide legacy /dev/psaux device ?
? Defined at drivers/input/Kconfig:72 ?
? Depends on: !S390 && INPUT && INPUT_MOUSEDEV ?
? Location: ?
? -> Device Drivers ?
? -> Input device support ?
? -> Generic input layer (needed for keyboard, mouse, ...) (INPUT ?
? -> Mouse interface (INPUT_MOUSEDEV [=y]) ?

Yup, it was built into the kernel. (A module would have [=m])

Modern systems use the 'evdev' X driver to accesses the '/dev/input/
event<X>' devices. Check with 'cat /proc/bus/input/devices'.

Ok. Mine is a module.

modprobe mousedev

ls -l /dev/input/mice
crw-r--r-- 1 root root 13, 63 Apr 16 19:18 /dev/input/mice

Ok, that fixed it. Cheers.

Mark.
