I'd like to use linux to sync my Kyocera 7135 smart phone. The problem is
that udev doesn't seem to recognize it correctly. When I plug the phone
in the cradle and hit the sync button /dev/ttyUSB0 and /dev/ttyUSB1 are
created but no /dev/pilot. I read the udev docs and can't quite figure
out what to fix. I know that I need to create a rules file that is parsed
before /etc/udev/rules.d/50-udev.rules. I believe that I have the
language of the files figured out. The problem is that I don't know the
values to look for. I was hoping to crib /etc/udev/rules.d/50-udev.rules
and place a modified version 05-marks.rules but can't find the lines
that create /dev/ttyUSB0 and /dev/ttyUSB1.

I also don't know the values of various SYSFS{whatever}. I tried udevinfo
on /dev/ttyUSB0 and /dev/ttyUSB1 and it isn't clear [output below]. Which
is the phone?

I understand that you can have a program executed depending upon what's
plugged in. I'd like to have a script that syncs the phone even when no
one is logged in.

TIA

udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful attributes
in the udev key format.
Only attributes within one device section may be used together in one rule,
to match the device for which the node will be created.
