No, still not answering the question I am afraid.  To repeat, what we
are looking for is an explanation of the output of lsusb, not how to
get even more information that we do not understand.
In other words, since I am apparently not explaining myself clearly, what does
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
mean?

Also Karl please do not reply to me directly, just send it to the
list, I do not need multiple copies of the email, and if I just reply
to your personal email then it goes to you rather than the list.
