You're losing me a bit here, as my build list calls out OTG (On-the-Go) cables from Cable Creations, and they're 8". Having proper OTG cables is important to this setup, in order for both power and Ethernet to be delivered. Obviously, the USB keystone jacks and USB A to Micro B adapters need to be passing all pins as well.
What exactly are you trying to accomplish at this point? Are you saying that the Ethernet adapters you purchased, combined with the PoE splitters aren't working -- or are you trying to switch over to the UCTRONICS adapters?
