Thanks for these ideas.

With some of the devices, they get power but nothing else. With some
devices they get nothing at all (and there is no activity in the logs,
where you DO see activity in the logs for other ports or other devices).
As to wrong drivers, ALL the devices work in at least one port, except
the possibly dud USB HDD enclosure, which works in NO ports but works in
all ports with a different drive in it. All the ports are USB 2.0/1.1
ports as far as I know, but that is an idea worth double-checking.

Regards, K.
