(A careful reader will notice that they can skip the restart part: all that required to get the descriptors in the capture file is to reconnect your device after capture has started.).

Question #1, is there any correlation between the 1.11.x address and the port-17 device seen in USBPcap? Can I filter in some way via the port-17 location? I then plugged the device back in and found it with the address 1.11.x. Next I disconnected the device and ran wireshark. ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter
