Description of problem:
I am trying to setup Fedora 23 from the net inst to a BeeBox.
I selected the KD Plasma 
Also I am trying to install to an attached USB drive, 16GB Kingston DT unit while my mSATA drive arrives. 

It should work, but I am getting this error. Seems to me like Anaconda is not recognizing this setup

Version-Release number of selected component:
anaconda-23.19.10-1
