Hi

I finally decided to give udev a try, but it was not as good as I hoped. I =

have Apacer Mega Steno card reader (as well as other usb storage device) an=
d=20
I wanted to have permanent name for it. Okay, lets create some rule in=20
udev.rules and script that will generate it. Sometimes the name was generat=
ed=20
correctly and sometimes not. Afer some experiments I got three rules, that =

seem to work (with line numbers):

21: BUS=3D"scsi", SYSFS{vendor}=3D"Apacer  ", SYSFS{model}=3D"Mega Steno   =
   ",=20
PROGRAM=3D"/etc/udev/apacer.sh %k %b %n", NAME=3D"%c{1}", SYMLINK=3D"%k %c{=
2}=20
%c{3}"
22: BUS=3D"scsi", SYSFS{vendor}=3D"Apacer  ", PROGRAM=3D"/etc/udev/apacer.s=
h %k %b=20
%n", NAME=3D"%c{1}", SYMLINK=3D"%k %c{2} %c{3}"
23: BUS=3D"scsi", SYSFS{vendor}=3D"Apacer", PROGRAM=3D"/etc/udev/apacer.sh =
%k %b=20
%n", NAME=3D"%c{1}", SYMLINK=3D"%k %c{2} %c{3}"

related udev log:

Why does every time match another rule?

Using udev 021 (from Debian unstable) and kernel 2.6.3.

Another topic is that device does not automatically report partitions, so m=
an=20
has to read appropriate device to get partitions.
