I have a switching USB hub that uses one (that's my daily interaction; it just sits there, taunting me). I've seen older electronics testing gear that uses them - I want to say it was a USBee logic analyzer?

I see all kinds of wild proprietary cables working with legacy embedded systems, but the non-standard USB A plug - USB A plug cable is the most obnoxious thing I come into contact with on a daily basis.

Happy birthday!
