Ahhh, now I know where my problem is.. Let me see why I cannot reproduce the error on my side; otherwise I may create more noise in my next patch set (customize device IDs/strings).. > Also long run I think best is going to have a child node per downstream > port, so we create a matching linux struct device.

Maybe a dumb question: what would be the proper place to parse the child node/properties when they are added? For example, in some usb_gadget_ops callback? Cheers, Tao
