Code:

live ~ # ls -l /dev/uinput /dev/input/uinput
ls: impossibile accedere a /dev/uinput: No such file or directory
ls: impossibile accedere a /dev/input/uinput: No such file or directory
live ~ # modprobe -v uinput
insmod /lib/modules/2.6.33-gentoo-r2-live/kernel/drivers/input/misc/uinput.ko
live ~ # ls -l /dev/uinput /dev/input/uinput
crw-r----- 1 root root 10, 223  3 lug 16:20 /dev/input/uinput
crw------- 1 root root 10, 223  3 lug 16:20 /dev/uinput

vengono creati due dispositivi!!
la cosa si può correggere con una riga di udev come la seguente:
Code:

live ~ # cat /etc/udev/rules.d/33-uinput.rules
KERNEL=="uinput", GROUP="users", SYMLINK+="uinput", MODE="666"

in questo caso, però, le impostazioni dei permessi non vengono passate:
Code:

live ~ # modprobe -rv uinput
rmmod /lib/modules/2.6.33-gentoo-r2-live/kernel/drivers/input/misc/uinput.ko
live ~ # udevadm control --reload-rules
live ~ # modprobe -v uinput
insmod /lib/modules/2.6.33-gentoo-r2-live/kernel/drivers/input/misc/uinput.ko
live ~ # ls -l /dev/uinput /dev/input/uinput
crw-r----- 1 root users 10, 223  3 lug 16:26 /dev/input/uinput
lrwxrwxrwx 1 root root       12  3 lug 16:26 /dev/uinput -> input/uinput

la riga di udev funziona solo parzialmente, perchè il MODE non viene applicato.

p.s.:
Code:

live rules.d #  uname -rm
2.6.33-gentoo-r2-live i686
live rules.d # udevd --version
158
