Issue with Attaching Audio Interface to PureData

So I am having issues with attaching my Audio Interface (Fasttrack) to PureData. When I process the adc~ signal it goes through my dynamic microphone to my computer no problem. Even with Logic Pro X the microphone processes through. However, when I plug it into Pure Data, I change the settings to (Fasttrack USB) and (Input 2) and the signal does not process through Puredata.

My connection set up is:

• USBC-> Shark USB Hub
• Shark USB Hub -> Fasttrack Audio Interface
• Fasttrack-> Dynamic Microphone

So I have an:

• OS Sierra
• Macbook Pro
• Fasttrack USB Audio Interface
• Shark USB Mic and Headphones attached to a USC-C Converter
• Dynamic Microphone (XLR->Quarter-inch)

Help? Suggestions?
