Well, an attempt to install kernel image 2.6.2-3 wanted to remove hotplug. I found an update for hotplug and did that and then 2.6.2-3 installed without complaining. This did NOT correct the usb-request-ubr -32 hangup on shutdown. I apparently can excape or time out of this but ... I noticed a long list of undefine module names on USB on bootup. Maybe all harmless.
