You are getting seriously full of sh*t here. Read again what Arnd said rather than twisting it to try to make your point. The age of the OF binding document for USB has no relevance. The fact that it's a very simple binding however does. As Arnd mention, nobody says that somebody/something has to generate a full and complete representation of USB for your board, that would be beyond the scope. However, it should be trivial to layout in the fixed part of the board device-tree nodes representing on-board (fixed) devices with the right amount of properties for allowing the linkage to happen between those nodes and the Linux usb_device object. Basically it boils down to one property afaik, "reg". That's about it (oh and possibly #address-cells and compatible for hubs that are on the way to the device if any). About 15mn of work if you are familiar with the .dts syntax, maybe twice as much if you are not.
