It looks like /dev/pilot is owned by you, but (iirc) the palms/visors
and such use /dev/pilot and one other USB channel to do the sync. Based
on your earlier comments, it look like it might require you to also
own /dev/ttyUSB0. One thing that you might be able to do is use

/etc/security/console.perms

Add the following entries (below the comments)

# device classes -- these are shell-style globs
<pilot> /dev/ttyUSB*

# permission definitions
<console>  0660 <pilot>     0660 root.uucp

Then log off and back in. This should set things up so that the person
logged in on the machine console (X or virtual console) will own these
devices.
