Howdy! Mark,

I use USB Hubs that come with a external wall wart power supply instead
of the power supplied by the computer to the USB Hub.

I figure if I want to plug some USB device in a Hub I don't want the
Hub to have insufficient power to run that device.

As usual I try to learn as much as I can.

I consider myself knowlegable enough about Computer Stuff to be
considered dangerous.

I am glad Your Friend figured out a work around to use his DELL.
Computers do get aggrevating at times don't they?
