Stranger udev.rules error

Question

I am trying to use my pda (Palm Tungsten E, but that should be irrelevant) under KDE.  Well, I do not get that far!
According to the standard udev.rules the PDA should be seen as a tty device with the rule
KERNEL=="ttyUSB[0-9]*", NAME="tts/USB%n"
Later there is a rule specifically for Palm Pilots
BUS=="usb", KERNEL=="ttyUSB[0-9]*", SYSFS{product}="Palm Handheld... ", SYMLINK+=pilot
(Should not the later rule be disregarded since a valid rule has already been encountered?)
However, I get nothing.  The messages.log tells
usb 3-2: new full speed USB device using uhci_hcd and address 2
usb 3-2: configuration #1 chosen from 1 choice
That's all. No devices (not even /dev/tts/USB1), no module loaded, nothing (that I can detect).
Connections etc are ok - in Slackware the PDA is connected at /dev/tts/USB1 (later rule disregarded!) and can be used as root. So no positive clue there.
So, what is different in Arch? HAL? and most important, what should I do?

Answer 1

Ok. Add usbserial and visor modules to the MODULES in /etc/rc.conf (as it seems they are not loaded automatically). Restart machine or run /etc/udevstart and replug your palm. Can you see /dev/tts/USBx now at least? (x might be different number each time you plug in your palm).
Note that the second standard rule that should create /dev/pilot link will not work for you because SYSFS{product} is different than yours and will not match with the rule.
Now create /etc/udev/rules.d/010.udev.rules file and put these rules inside (there are two lines only! watch out for forum line wraps):
KERNEL=="ttyUSB[0-9]*", NAME:="tts/USB%n", GROUP:="users"
BUS=="usb", KERNEL=="ttyUSB[0-9]*", SYSFS{idVendor}=="0830", SYSFS{idProduct}=="0060", SYMLINK:="pilot"
Restart machine or start /etc/udevstart and replug your palm. It should create /dev/tts/USBx and /dev/pilot (which you should use in palm applications). The owner for /dev/tts/USBx should be root:users. If it needs special write permissions you can add
, MODE:="0660"
to the first rule in /etc/010.udev.rules file. You can of course change "users" to any group you like just remember to add your user to this group.
BTW If you have too many modules loaded you can customize /etc/mkinitrd.conf - check wiki for details.
