Hi guys,
I've had this issue crop up recently whereby one of my USB-C ports (back-right) is completely disabled. It won't recognise the charger, it doesn't recognise external monitors, and it doesn't recognise anything USB. I do however get the "USB Accessories Disabled - Unplug the accessory using too much power to re-enable USB devices." warning when I plug in a thumb drive (Kingston DataTraveler microDuo) or my iPhone 6 using an Ailun USB type-A to type-C adapter, but only on that port! These are recognised normally on all other ports.
Diagnosis: Nothing shows up under system information when plugged into that port. I've tried an NVRAM reset and an SMC reset, and neither seem to work either - although I'm not sure I'm performing the SMC reset correctly - nothing seems to happen when I hold cmd+opt+shift + power for 10-20 sec (powered off).
Not sure if there is anything else I can do other than take it in to the shop, but I'm all ears to suggestions/thoughts!
