Re: USB devices with same vendor:product id

Quoting Ján Tomko (2020-02-03 14:45:38) Regarding that patch, as I mentioned in another reply, *USB* bus numbers on Linux aren't stable -- see <https://github.com/torvalds/linux/blob/master/drivers/usb/core/usb.c#L629... ("Each device's dev->devpath will be stable until USB is re-cabled, and hubs are often labeled with these port numbers. The name isn't as stable: bus->busnum changes easily from modprobe order, cardbus or pci hotplugging, and so on.") So unless it uses PCI devpaths, which from a quick glance at the code I don't think it does, that doesn't actually solve the problem of changing *bus* numbers -- it only solves the problem of changing *device* numbers under an assumed-to-be-but-not-actually stable bus. -- Pol
