Even though you are starting the driver as root, it drops to the
unprivileged user selected by the configure script. So ugen1.4 is
probably the only device it can open.

Also note that the driver can only see the devices that libusb
enumerates. I don't know if the BSD libusb uses the USB_DEBUG
environment variable, but that might show more detail.
