In the event of a sudden USB reset, the device will be redetected on the same port and at that moment the drive letter will change, but the port NUMBER will not. by-path references the physical hardware port number and maps it to whatever drive letter happened to get assigned. Is this not exactly what you are asking for? I don't understand why the /dev/disk/by-path links are so invisible to people when it is literally the solution to this type of problem. -Ben
