My display's USB ports and charging cable not working
I have a 27" Thunderbolt Display. About a year ago, the display's charging cable stopped working, so now I use an independent charger to power my MBP while it's connected to the display. And now all three USB ports on the display no longer work.
The display itself works fine connected via Thunderbolt to my MBP.
Does anyone know what might be going on and how I could fix the problem?
