I tried to use USB mon as you say and got a nice file I hope will give some
clues.

I did:
- start monitoring the whole bus (cat 0u);
- plug the USB hard disk device;
- suspended the devices:

echo devices > /sys/power/pm_test
echo mem > /sys/power/state

This freezes all processes and suspends all devices for 5 seconds.

- stop the cat process.

The resulting file is appended.
