It is not hard to create a udev rule that will always create a
symlink named something like /dev/wince every time you plug in the
pl2303, regardless of the order you plug in the device. If you
always use the same cable, you can add the serial number to the
rule, so that only the specific cable gets the symlink...

One thing to be careful of is that you need real status lines in
order for the sync to work correctly. Not all USB to serial adapters
support this. If the iPAQ says it is connected as before the adapter
is plugged in, or as soon as the adapter is plugged in, even if the
sync software in not running, then your adapter does not support the
status lines, so syncing gets to be interesting. You may be able to
get the device to sync, but it becomes a matter of luck and timing,
instead of being controlled by the status lines.

The vdccm and the dccm programs do basically the same thing. Dccm
comes from the synce package, and vdccm comes from the synce-kde
package. The big difference is that vdccm allows more then one
device to connect at the same time. You need to follow the synce and
not the synce-kde instructions if you are using dccm.

You ether need to get the synce-kde package, or use the synce
instructions. The packages are the same. There is enough difference
to cause you problems. Also, the way you troubleshoot the two
packages is somewhat different. The other thing to be aware of is
that the synce-kde instructions are geared more to a device that
plugs into the USB bus directly, and not one that user a USB to
serial adapter. If you have a standard serial port, you may want to
use that instead of the USB to serial adapter. If you have a USB
synce cable for the iPAQ, that should work as well, and create what
looks to the system as a USB serial port.

One other point - after you have established a "trust relationship"
between the iPAQ and your Linux box, you can use a network
connection to sync as well. I have an old Itronics T5200 that I have
used this way. I used to synce it to my Mandriva desktop. Now that I
have converted the desktop to FC6, I have to set this up again...
