hi there,
i alwayys have troubles with my usb mouse after kernel updates. first of all, i will explain what i did.
i emerged the new gentoo-sources and copied my old config to /usr/src/linux. then i made a and compiled the kernel and installed it (handbook).
with my udev-rule | Code: | | BUS="usb", SYSFS{idProduct}=="c00b", SYSFS{product}=="USB Mouse", NAME="input/%k", SYMLINK="input/usbmouse" |
with kernel version 2.6.13-r5 my mouse got recognized without any problem and i configured it in /etc/X11/xorg.conf like follows | Code: | | Option "Device" "/dev/input/usbmouse" |
. but with the newly compiled kernel (2.6.15-r1, but also before 2.6.14-r5) this does not work anymore. i changed my xorg.conf to | Code: | | Option "Device" "/dev/input/mice" |
and the mouse works fine. why is that so and do i need that rule in the first place? i heard, one should use a udev-rule, because if i use | Code: | | Option "Device" "..../something" |
and the mouse gets plugged in and out, it does not have the same name anymore necessarily. so with the rule i make sure, that my mouse can always be configured as | Code: | | Option "Device" "/dev/input/usbmouse" |
. is that right or is "..../mice" sufficient? if a udev-rule is recommended, can anyone help me with my problem? thanks,
homry

theres not much point in a udev rule for mice, since all mice are aggregated to /dev/input/mice

ok, thanks. that is good to hear. so i can never go wrong with | Code: | | Option "Device" "/dev/input/mice" |
. that makes things easier.
in the german gentoo-wiki i got the info, that it can be useful to make a rule for your mouse (http://de.gentoo-wiki.com/Udev), but maybe i got that info wrong. practice, however, tells me that you are right  .
