PLACE directive subsumed?

PLACE directive subsumed?

[Jeremy McBane]

Hello,

I need to make udev rules for multiple, identical multi-port
USB-to-serial converters so the converter that's attached to a certain
USB port will always be assigned the same device nodes (or symlinks in
my example below).

In the past I was able to use the PLACE directive to do this.  For
example (for a 4-port converter):

     BUS="usb" SYSFS{idVendor}="1608" SYSFS{idProduct}="0201"
SYSFS{serial}="*-0" PLACE="1" NAME="%k" SYMLINK="ttyEDGE4_A_0_%e"
     BUS="usb" SYSFS{idVendor}="1608" SYSFS{idProduct}="0201"
SYSFS{serial}="*-1" PLACE="1" NAME="%k" SYMLINK="ttyEDGE4_A_1_%e"
     BUS="usb" SYSFS{idVendor}="1608" SYSFS{idProduct}="0201"
SYSFS{serial}="*-0" PLACE="2" NAME="%k" SYMLINK="ttyEDGE4_B_0_%e"
     BUS="usb" SYSFS{idVendor}="1608" SYSFS{idProduct}="0201"
SYSFS{serial}="*-1" PLACE="2" NAME="%k" SYMLINK="ttyEDGE4_B_1_%e"

        ln -s /dev/ttyEDGE4_A_0_  /dev/ttyA1
        ln -s /dev/ttyEDGE4_A_0_1 /dev/ttyA2
        ln -s /dev/ttyEDGE4_A_1_  /dev/ttyA3
        ln -s /dev/ttyEDGE4_A_1_1 /dev/ttyA4
        ln -s /dev/ttyEDGE4_B_0_  /dev/ttyB1
        ln -s /dev/ttyEDGE4_B_0_1 /dev/ttyB2
        ln -s /dev/ttyEDGE4_B_1_  /dev/ttyB3
        ln -s /dev/ttyEDGE4_B_1_1 /dev/ttyB4

The problem I'm running into is that PLACE doesn't seem to be supported
in newer kernels (newer versions of udev?), i.e. Fedora 7.  How would I
achieve this on a Fedora 7 box?

Thanks in advance,

-Jeremy

Try KERNELS="*1" (or for udev older than 098, use ID=).

Also drop the useless NAME="%k", use '+=' for SYMLINK or it will
drop previous symlinks, use '=' for all matches, and use a ',' to
separate the matches in the rules from each other.
