But the device tree path on applies to devices coming from the device tree and doesn't apply to usb devices generally. So, I reverted the whole deal. The usb bus has it's own idea of a hardware path, but that should be selected by adding a different but similar ioctl to the one which specifies a device tree path. Same goes for choosing by serial number. -- Frank
