It shuts off power to the USB ports according to my USB V/A meter, for about 2 seconds ... of course that doesn't exclude a USB initialisation from also being sent.

Someone very generously donated the money (thank you!) for the powered hub, so that made the choice easy. I'll report back with the results in a few days.

Deozaan:
I went to order that powered USB hub and then noticed the reviews were not favorable. So, thanks (again) to the generous donation I decided to spend a little more and get this one instead. It has the added benefit of having USB 3.0 ports. :Thmbsup:

It works!  :Thmbsup:

Thanks for the idea, mwb1100! And thanks once again to the person who donated! :Thmbsup:

Glad it worked - to be honest I wasn't sure if when the computer booted up it would perform some initialization that would reset the USB hub and drop power on the ports for a moment.
