Hmmmmm, I have a computer with the female mini-DIN connectors for Mouse/green Keyboard/purple. Have you ever seen those?

I never use these connectors because I use a USB dongle for wireless mouse and keyboard. Aside from the color, they look identical to the female mini-DIN connectors on a Hi Pro. Perhaps our industry professionals who have been using Hi Pro’s all these years have never thought of connecting a pair of hearing aids to a computer using the mouse and keyboard ports?
Maybe you could try connecting the left hearing aid to Mouse/green and the right hearing aid to Keyboard/purple and see what happens.
If you do get a connection and the fitting software says the left/right hearing aids have been switched, then all you need to do is switch the left hearing aid to Keyboard/purple and the right hearing aid to Mouse/green.
Have you tried that?
