    I had a small MIDI keyboard plugged in and got a notification saying that it was drawing too much power. The ports were disabled and now I only have 2 of the 4 USB ports working. Tried the SMC reset, didn't work. Turned the computer off for a couple hours and it's still disabled. I find it hard to believe that this small MIDI keyboard would break these USB-C ports. Does anyone have a solution to this?

    Maybe try a PRAM reset. It is different on the 2016 MacBook Pros, https://support.apple.com/en-us/HT204063

    Also, I assume you have disconnected the keyboard? And will connect it via a powered hub in the future.

    Still dead after the PRAM reset. I tried connecting other devices on the ports but they don't seem to work as well.

    Did you do a SMC reset? If after SMC still not fix the USB port take to Apple it should cover under warranty?
