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.
