Is it me or ArcGis try to connect GPS only on COM port?
I surely made a mistake ( maybe i didn't catch something )
Today it's all on USB connexion
Of course i find something else to go on but it's so clumsy ....
Is this what you are referring to ArcGIS Help (10.2, 10.2.1, and 10.2.2)
When the ArcMap GPS toolbar was introduced most GPS devices would have connected via COM port. I don't think the toolbar has been updated to handle USB devices. ESRI should seriously consider updating the toolbar as almost all consumer GPS devices are now USB.
I just came across this blog post by Esri Australia that might help:

We may have to do the same thing. I sure hope not though.
