I assume that these options are indented? They should be.
Also, looking at the docs, there should be a USB after -P.
Interesting! I see that second config file option, sadly I have no idea where it comes from. 
I see that too. Again, I don’t know where it’s coming from either.
However, give the -P option a USB parameter, as above, and see if that makes any difference.
If it still gets extra config files, and protocols, I’m afraid to say that “I’m stumped”.
Cheers,
