Traditionally each device automatically had a file under /dev, but this behaviour was not really nice because several devices do not need a file. I changed this so that files under /dev have to be explicitely registered. What you see with the devinfo command are the devices registered in the system and in brackets the /dev files registered from these devices. so for example the device 'miiphy0' has registered a file /dev/phy0. usb0-2 is a device registered for housekeeping only with no files at all, that's normal.
