You didn't say *what* you tried with devfs.rules.  This is what I use
(because I am the only user of this machine, so security is not a
problem; these might not be good for a shared machine):

[localrules=10]
add path "ttyU*" mode 0666
add path "cuaU*" mode 0666
add path "ugen*" mode 0666
add path "usb/*"  mode 0666
add path "usb" mode 0755
