I won’t get into all the usage of WireShark in this post. This will bring the USB interface “down.” When you are done with your Capture Session, just return to Terminal and paste: Sudo ifconfig XHC20 down. Now, as you can see, Wireshark sees the XHC20 USB Interface, and can now capture its traffic. So at the command prompt you’ll paste in: Sudo ifconfig XHC20 up. In most cases, this interface is called XHC20. But 1st you’ll need to open Terminal so you can Enable, or “Bring Up” the USB Interface, such that WireShark can see it as a Capture Device. Once you’ve downloaded and got Wireshark installed, it’s easy to capture USB traffic. Until there’s official support, you can still get USB capturing going with Wireshark, by downloading the “nightly build” version, which is available here: In order for a capturing protocol to be included in Wireshark, it has to go through quite a rigorous review process. I guess you’d classify this as an unofficial release. Remember you will not be able to capture network. Hit the super key and type wireshark in the search bar.When the icon for the Wireshark appears, click on it to launch it. If you are logged in as a root user, you can also launch Wireshark form the GUI. However, Apple has enabled capturing USB traffic, even for USB-C devices, via Wireshark. In order to launch Wireshark, issue the following command in Terminal: sudo wireshark. Afterwards the connection should be established, and whenever something happens on the USB, you should see related packages in wireshark.As developers know, the utility tool to debug and monitor USB Traffic hasn’t been available for quite a while. Once you run the command, you need to login via SSH first (e.g. Then run the following script on your PC to launch tcpdump over ssh, and pipe its output into wireshark. Enable SSH and configure it so you can login with your PC's SSH key as root on your phone. 1.wlan0 2.any (Pseudo-device that captures on all interfaces) 3.lo 4.usb0 5.usbmon5 (Raw USB traffic, bus number 5) 6.usbmon4 (Raw USB traffic, bus number 4) 7.usbmon3 (Raw USB traffic, bus number 3) 8.usbmon2 (Raw USB traffic, bus number 2) 9.usbmon1 (Raw USB traffic, bus number 1) 10.usbmon0 (Raw USB traffic, all USB buses) 11.nflog (Linux netfilter log (NFLOG) interface) 12.nfqueue (Linux netfilter queue (NFQUEUE) interface) 13.wwan0 Capture Over SSHĪ convenient setup is running wireshark on your PC and have it analyze the traffic in real time.
