I have tested this for all 6 build positions (CONFIG_USB = n, m, y and
CONFIG_USB_MON = n y) with a positive result. But I thought the help
wordage was not quite what we needed, and the reference to USBMon was
incorrect. So, the attached is just a little different.
Adrian, how about this?

This makes the configuration of USB_MON less confusing.

If you say Y here, a component which captures the USB traffic
between peripheral-specific drivers and HC drivers will be built.

- This is somewhat experimental at this time, but it should be safe,
- as long as you aren't building this as a module and then removing it.
