Note that while for you it might be sufficient to have a hard coded link from /dev/pilot to /dev/ttyU0, that is not necessarily the case if you have multiple USB serial gadgets. The way I handled it is by using an entry in /etc/usbd.conf: # # Fixup permissions for Palm Handheld ucom devices # (set here and not in devfs.rules since we only want to apply # the change to Palm com ports, not all USB com ports) device "PalmHandheld" devname "ucom[0-9]+" vendor 0x0830 attach "/bin/chmod 0666 /dev/${DEVNAME} ; /bin/ln -s /dev/${DEVNAME} /dev/pilot" detach "rm -f /dev/pilot Having said that, it would be great to be able to create links from devfs.rules - I'd certainly use it for my /dev/cdrom entry!
