The physical topology underneath each host controller is stable but bus numbers (usb1, usb2 etc.) are not. For onboard host controllers it could be possible to anchor to a PCI or platform bus device. But busses on expansion cards can't be recognized so easily without using maybe serial numbers - which may be cloned across multiple devices - we can't know. > This would give user-space a persistent identifier for the connector: > if the user plugs in a USB display on a given port, the PATH would be > the same even if the machine rebooted or the displays were plugged in > in a different order. How about using e.g. the serial number of the gud USB device instead of host topology, or maybe some other information from the panel behind it? //Peter
