I have answered this question in your other post (viewtopic.php?f=5&t=49235)

I would suggest buying a mains powered USB 2.0 Hub. It MUST be USB 2.0 not USB 3.0/2.0.

What LVAR are you trying to program specifically? I have done a fair amount of work on the 757 and MAY be able to assist.

Are the USB hubs 2.0 or 3.0? Is the USB port on the PC 2.0 or 3.0. Unfortunately the FIP's require 2.0.
