>Ok, what process do you use to run the development code?

that shouldn't matter for your issue but, since you asked:

I invoke run-brltty as root. I've defned the brltty user so, even though brltty starts as root, it drops privileges by swithing to the brltty user. I wrap brltty with a small script to make it easy for me to test different braille devices (attached).
