STM32F7 Discovery: Encoder Interface & Getting access to PA9

I'm trying to get the encoder interface operational on the STM32F7 Discovery Board. Unfortunately, there seems to be a lack-of-pins problem. It seems like the easiest timer to use is TIM1. Channel 1 is on the arduino header, so that's good. However, the second channel is on PA9...which appears to be on the normal micro USB slot.

I'm not using that USB for anything. However, I'm also not able to figure out whether there's something in the way that will mess things up.

Does anyone have experience with getting the encoder interface up and running on this board? I don't want to start with green wire fixes unless I'm 100% they're needed.
