Right. So far I've modprobed visor, and got no errors back, so that
would mean the kernel would support my palm. Oh, b.t.w. I've got a palm
m500. I've also tried making a node /dev/ttyUSB0 as well
as /dev/ttyUSB1. Both did not work so I removed them just in case udev
wants the nodes. 

Getting nowhere manually I've looked into udev.
udevtest /dev/ttyUSB0 returned:

version 050
looking at '/dev/ttyUSB0'
sysfs_open_class_device_path failed

udevtesting /dev/ttyUSB1 returned thesame (looking at /dev/ttyUSB1
offcourse). I don't know if I used udevtest correctly, but the man page
doesn't make things much clearer also.

The only thing left to do (afaik) is making the udev rules myself. From
what I can figure out of the documentation I need the serial number.
Does anyone know how I can figure that out?

Also, this seems a lot of work for just syncing with a palm. Is this
normal for any new hardware? I can't call this very userfriendly. Is
there maybe a frontend that can automate detecting hardware and
configuring udev rules? If not, I just hope I can get my webcam working
before christmas ;)

Anyway, thanks for the responses so far.
