I have several midi to 1/8 and the only one that works is the one that came in box. None of the others work. I tested them on other devices. Any thoughts? Can someone test this. I am in V2.10 os version, but that should not matter. This is a hardware issue.

Until recently, there were two competing implementations of MIDI over 3.5mm TRS jacks.  
They are known as Type A and Type B.

We use Type A, which is the one that the MIDI association chose as standard.  
My guess is the others you own are Type B adapters.

Here’s a good resource that has a large inventory of gear and which standard they use:
