For a palm pilot, you need a kernel module that knows how to talk to
them.  For mine, the 'visor' module does the stuff:

# modprobe visor

I believe this should work with your m130 too.

Once you've loaded the module (put it in /etc/modules if you want it to
load every time), tail /var/log/messages and hit the sync button.

Your palm will talk to your computer and be assigned a serial port.  It
will look like:

Mar  2 17:31:54 pecorino kernel: hub.c: new USB device 00:03.1-2, assigned address 6
Mar  2 17:31:54 pecorino kernel: usbserial.c: Handspring Visor / Treo / Palm 4.0 / Clié 4.x converter detected
Mar  2 17:31:54 pecorino kernel: usbserial.c: Handspring Visor / Treo / Palm 4.0 / Clié 4.x converter now attached to ttyUSB0 (or usb/tts/0 for devfs)

You can now tell your sync program (jpilot or kpilot or whatever) to
use /dev/ttyUSB0 or whichever serial port you've got.

Very irritatingly, you MUST hit the sync button before running your sync
program, because it doesn't get allocated the serial port until you hit
sync.  The usb modules get all confused if you try to use /dev/ttyUSB0
before there is something on there.

Cheers,

Doug.
