It is fully functional with the K2 but when I try using it with FLDIGI nothing works ? no frequency control, no PTT, nothing! By this I mean that I am trying to use FLDIGI for the control. I have verified that I have all the correct settings in both FLDIGI and FLRIG with the ham that has been helping me. As a sanity check I installed FLRIG on my Windows machine and successfully ran FLDIGI there.

What version Fldigi, Flrig and Hamlib?   Also, what exact OS on the Pi?

Did you build Fldigi/Flrig from sources, or pulled from a repository?  
Sadly, the repo' versions are often out of date.

The best place to ask for help, would be the LinuxHam list on Groups.io.
