USB issue when connecting multiple devices with the same label

  1. I've encountered a rather odd behaviour when connecting multiple external USB devices which bear the same label. In this case: USB Ethernet adapter.
    All those adapters have an index appended tp them automatically when they are connected to differentiate them.
    The issue is that if I try to connect any of them to the guest OS, the one with the lowest index gets connected to the guest OS no matter which one I picked.
    Steps to reproduce:
    1 - Connect the USB devices to Mac.
    2 - Go to: Parallels menu bar menu --> Devices --> External devices --> Select your device (one that does not bear the lowest index for that given label)
    3 - The device with the lowest index for the given label will get connected to the guest OS.

    I've been able to workaround this issue by using the USB connection preference and binding those adapters I want connected to the guest OS there. When doing this, the correct adapter gets connected to the guest OS.

    Work Around:
    1 - Open the USB Connection preference dialog.
    2 - Add the device you want to connect to the guest OS.
    3 - Identify the guest OS to which you want to bind that device.
    4 - Unplug the USB device
    5 - Plug the device back
    6 - The device will now be connected to the guest OS.
