Try PN87520-S in the con-berg library, or better yet, learn to make your own.
Ah, thanks, no clue why that one didn't show up when I was just searching "USB"
I might try making my own parts sometime, but I'd have to find appropriate models for raytrace if I wanted to render it.
edit: there, much better.
For those interested it's a little USB breakout with a DIP switch letting you turn on or off each connection, if you turn off VBUS you can use a multimeter to monitor current.
