Yes - /dev/ugen? is the control endpoint - if your device only supports
controll transfers that's all you need.
Otherwise you may need /dev/ugen?.? for the endpoints, but
./MAKEDEV ugen1 will also create /dev/ugen1.1 to ugen1.15.
While ugen0 uses /dev/ugen0* node ugen1 uses /dev/ugen1*, and so on.
So if your are using 6 devices of ugen type at the same time you want
to have at least /dev/ugen0 to /dev/ugen5.

You can create them forhanded.
No need to wait until you really need them.
The following will create ugen0* to ugen19*:
cd /dev && jot 20 0 | sed 's/\(.*\)/.\/MAKEDEV ugen\1' | sh
