I've done that!! So much for poka-yoke.
I have a laptop and I plug in a USB RF Mouse and Keyboard when I use it at home.
This morning neither worked. Had me head scratching a bit there for a while.
Anyone ever notice that the RJ-45 network jack is exactly the same width as a USB plug???
It felt right sliding the USB plug in without looking 'cos I knew exactly where the USB jack is. DUH.

RJ-45.... RJ-46... Whatever it takes...
(line from the movie Mr. Mom where he says something like "220... 221... whatever it takes." ... during a voltage discussion.)
