Hmm, I never actually used the usbmon program. I did "modprobe usbmon",
then Wireshark shows usbmon{1..4} (one for each bus) as an interface
like eth0 for ethernet. http://wiki.wireshark.org/CaptureSetup/USB

If it's difficult to compare two captures in Wireshark (I don't know any
other method than visual inspection), tshark (Wireshark's "command-line
counter-part") is able to decode to stdout. Maybe one can run the diff
program on that. The output seems a bit terse however.

Please be aware: in my Wireshark (1.10.2) one of the of the SCO setup
packets are decoded slightly wrong. It looks like Wireshark is missing
a BDADDR in the beginning, so all the other fields get shifted.
