Yes, the device only registers on the USB bus when the hotsync button is
pressed (thus activating the hotsync app on the palm), and deregisters
when the hotsync app finishes.

Most Palm devices register two serial devices. Generally the second one
is the one that you use for hotsyncing.
First get it working without trying to create special device names:
1. Type the command "pilot-xfer -l -p /dev/ttyUSB1" (don't press return
yet)
2. Press hotsync
3. Press return on your pilot-xfer command and you should see a list of
the databases that are on your Palm.
4. If it doesn't work, try /dev/ttyUSB0 instead.
To make udev create a specially-named device, do the following:
1. Press hotsync
2. Run the command "udevinfo -a -p $(udevinfo -q path -n /dev/ttyUSB1)"
This will display a bunch of stuff. Look for a key that udev will be
able to use to uniquely identify your Palm and not mistake it for
some other USB device (including other Palms). I use the serial
number.
3. Create a file called /etc/udev/rules.d/00-local.rules with the
following contents:
SYSFS{serial}="your-serial-here", KERNEL="ttyUSB*[13579]", SYMLINK="palm"
This tells udev that when a USB device with the specified serial number
and an odd-numbered ttyUSB device shows up, that it should create a
symlink named "palm" to that device.
It's not perfect. For example, if you have other USB serial devices,
then you would probably want to create a symlink to the even-numbered
device, depending on how many serial devices were already on the
bus. But it works for me, because all of my serial USB devices are palms.
