Hi guys,

Found an earlier post about opening USB interfaces in wireshark (https://stackoverflow.com/questions/1...).

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

Unfortunately, after disabling SIP the problem still exists where Wireshark will no longer recognize my USB C Ethernet adapter ONLY after updating to macOS 10.15.2 Catalina (that specific update, not the previous Catalina version).

What isnt working: Wireshark recognizing usb interface after updating macOS to 10.15.2 Catalina.

What am I using: MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) on 10.15.2

What I tried: Disabled SIP from recovery mode > terminal > csrutil disable > enter > restart > launch Wireshark
