SM-G928A Driver Issue

I have 2 Galaxy S6 Edge+ for AT&T. One is on firmware G928AUCU2APB2 and the other is on G926AUCSAPE3. The one on APB2 no problem, was able to clear FRP and unlock etc. The second one on APE3 won’t load drivers, when plugged in Device manager shows:

"Unknown USB Device (Device Descriptor Failed)"

Tried in Download and Android mode, same problem. Tried on 3 different PC’s, same problem. I don’t think it’s a driver issue because the other S6 Edge + works fine. Doubt it’s a firmware issue, so I am assuming a hardware problem?

Any ideas?
