Hey. Trying to connect my magstripe reader using the headphone jack.

There's no button or light on the reader. 

It's not showing up on the POS app. 

How to get it connected?

It should 'just work' when plugged into your headphone jack.  Did you grant the Square app all of the permissions it asked for when you first launched it?  If I recall, it'll ask you for permission to access your microphone.  I believe this is necessary to properly utilize the Square magstripe reader.
