What is VTAP10?

[Altera_Forum]

Hi guys. So I have my Max 10 development kit installed and am checking to be sure I have the drivers installed properly. Quartus Prime 17.1 is running fine. :cool: 

 But now I have what seems to be a problem.   The Intel Max10 Dev board runs the included board software OK, when it comes to using the programmer, I have questions.  I have been able to get a simple design to program and run, but only after fiddling with 'auto-detect', and removing a detected hardware called VTAP10. There is no VTAP10 showing up in the tutorial demo I followed, but the tutorial was using 15.0.   I could use a little help. What is VTAP10 and how does it fit into the picture? Is the VTAP10 hardware part of the Altera/Intel Development board, or am I looking at a bad USB-blaster driver install or other mess up? What documentation should I reference to understand this part better? Thanks for your help.
