 ***/etc/devfs.rules:
 [localrules=10]
        add path 'ugen*' mode 0660 group operator
        add path 'usb/*'  mode 0660 group operator
        add path 'usb' mode 0770 group operator

 ***/etc/rc.conf:
        devfs_system_ruleset="localrules"

+ add your user to the operator group or change the group name above
to match your needs :-)

+ # service devfs restart

all shoud work now as expected :-)
