According to a few things read on the web I have to load the garmin_gps
module. I did it with succes but the documentation found said to use
/dev/ttyUSB? which device I don't have. Maybe I still have a few things
to
understand about the USB devices and udev!

I would like to know if someone have been able to communicate with a
Garmin
GPS via a USB port and how you did it. Or maybe someone with a good
understanding of USB and udev could help me understand what is going on
and
what I should do to make it work.

Your documentation may not have taken udev into account. Assuming that
you're using standard Etch, run tail -f /var/log/syslog and then plug in
the gps and see if a message appears that tells you what device it
connects to. I've never hooked my GPS up to the computer. However, for
comparison, my Palm comes up as something like /dev/pilot.

Ok, here is what I got from syslog:

Aug 29 21:53:15 zherc kernel: usb 1-2: USB disconnect, address 3
Aug 29 21:53:28 zherc kernel: usb 1-2: new full speed USB device using
uhci_hcd and address 4
Aug 29 21:53:28 zherc kernel: usb 1-2: configuration #1 chosen from 1 choice

Do you seen something useful from this?

Here is what syslog shows when I plug in my usb GPS puck.
Aug 30 10:27:15 buddy kernel: usb 1-5.4: new full speed USB device using ehci_hcd and address 4
Aug 30 10:27:15 buddy kernel: usb 1-5.4: configuration #1 chosen from 1 choice
Aug 30 10:27:15 buddy kernel: pl2303 1-5.4:1.0: pl2303 converter detected
Aug 30 10:27:15 buddy kernel: usb 1-5.4: pl2303 converter now attached to ttyUSB0

Try doing a modprobe ehci_hcd _before_ you plug the Garmin in.

lsusb here shows
