All of a sudden my USB port does not read my chip and the port is dead, no power at the port. Everything else seems to work fine. Doe we know which fuse controls this?

 

The USB takes it's power right off the ACM, no fuse for the USB. The wiring could have come off the back of the USB port, which woudl make it inoperative.

2016 is under warranty though, just call your dealer and tell them it's dead.
