Hi guys,
Found an earlier post about opening USB interfaces in wireshark (https://stackoverflow.com/questions/13827224/sniff-usb-traffic-on-a-mac).
However, it seems that in macOS Catalina this is not possible as when running the ifconfig to pull the USB interface up it gives: ifconfig: interface HSO20 does not exist
Has anyone found a way around this? My tcpdump -D is here showing the interfaces:
1.en0 [Up, Running]
2.p2p0 [Up, Running]
3.bridge0 [Up, Running]
4.awdl0 [Up, Running]
5.llw0 [Up, Running]
6.utun0 [Up, Running]
7.vboxnet0 [Up, Running]
8.en1 [Up, Running]
9.utun1 [Up, Running]
10.en2 [Up, Running]
11.utun2 [Up, Running]
12.utun3 [Up, Running]
13.lo0 [Up, Running, Loopback]
14.gif0
15.stf0
Thanks David
