Hi Rich,

I've added some thoughts in line.

Did you have to update the start_trace.sh script and remove the space between the dash and the i? start_trace.sh didnt work for me until I did that
tshark - i usbmon$bus -w cap.pcap
vs
tshark -i usbmon$bus -w cap.pcap

Just ensuring that you are compiling tidy.c using the info at the wiki: https://chirp.danplanet.com/projects/chirp/wiki/DevelopersUSB_Sniffing_in_Linux

This doesn't help but I can reliably crash tidy with the non-tsv file so, maybe open up the TSV file in a text editor and ensure it "looks good"?

The c file is written with a pretty high expectation that the TSV file is perfect so I suspect the TSV file formatting.

What version of tshark are you using (tshark --version from a command line should be sufficient)
