is it ;debugOn or ~debugOn on the 4? I don't know
Then one would type ~usbNetwork (or ;usbNetwork)
you are mixing your prefixes for a start. it is either ; or ~ (no 4 can't check)
About DIAGS: NO! diags is totally separate to anything to actually "do" with the networking. although it does have a section for networking in it. (which is what I originally thought you were talking about)
"DIRECT" answer to my question(s):
So. Things to find out: is it a ~ or a ; on a 4...
(I thought it was ; but I may be wrong, I'm going to type ; from now on)
you could run a ;dm (dumpmessages?) to grab some logs and check the debugOn is working (I think that is right)
assuming it was a ; you would type ( in the search bar)
That should initiate the process. then you would try to connect.
