[gentoo-user] Problem with udev

[gentoo-user] Problem with udev

[jcd]

Hi. 
I read lot of articles about writing udev rules. But I don't know why my
local rules don't work :(.
I have Thomson LYRA mp3 palyer. Currently I have it like /dev/sdc (I
don't know why, but there isn't any sdc(n) indicating partition. When I
mount /dev/sdc to some mount point it works (vfat)). Here is udevinfo:

------------------------------------------------------------------------
$udevinfo -a -p /sys/block/sdc

Udevinfo starts with...

And this is my rule stored in /etc/udev/rules.d/10-local.rules

#Thomson LYRA

------------------------------------------------------------------------

It must be ok, I think, but when I plug in my mp3 player it don't work.
I tried lot of things but it is till bad.
Finally i decide to ask for help. Thx

Thank you very much. It is OK now. However, I followed this
documentation and there is described my approach (bad approach)
http://www.reactivated.net/writing_udev_rules.html .

Some of the sysfs naming has changed since that page was last updated.
