$ tshark -r file_with_captured_packets.pcapng -2 -R 'sysex' -T fields \ First column represents the source, second the host and last one is the SysEx data. I used tshark with sysex filter to analyze captured packets and show only important data.
Knowing that, I could take a closer look. It’s nothing special for a synthesizer, after all.
So I started sniffing, connected the device, launched the application and changed some settings.Ī quick look at the captured packets in Wireshark and I discovered that Microbrute uses MIDI SysEx protocol. This will capture the USB enumeration (more on USB enumeration can be found in chapter 4 here) packets that are used for proper packet dissection in Wireshark. Step 2 contains a really useful tip I omitted at first: after identifying the root hub you will sniff on, disconnect the device, start sniffing and then connect the device. I set up a capture process on a Windows machine as described on USBPcap’s website.
