There is a program that will display all the USB devices a PC has
used, along with other information. I can't think of the name right
now, and it's not on this hard drive. It's my backup system that I use
to program ICs.

It's called Device Manager. All you need to do is select View -- Show
hidden devices, and expand the USB section.

This listing isn't available until you set a system variable. I forget what
it is.
