I'm going to refine your description:
>The Braille sense has a USB mini port for connecting for use as a braille
>display.
It'd have a female USB mini device port.
>The phone has a USB micro port.
It most likely has a female USB micro otg port.
>I have a USB to mini adapter. Female full size USB on one end, male mini on
>the other.
That'd be a typical USB host extension cable for converting from a standard
plug to a mini plug.
>The cable from the braille sense plugs into this. The mini end of the adapter
>plugs into a mini to micro adapter, which then goes into the phone.
That won't work. USB isn't symmetric, i.e. one end - the phone, in this case -
needs to act as the host. The way you've done it, the phone is still acting as
a device rather than as the host. That's why you need an otg cable.
Get an otg cable. It'll be short with a micro male for the phone end, and a
standard female at the other end. Connect the Braille Sense cable to that.
>Perhaps too much daisy chaining?
No, just incorrect chaining.
