I’m on a MacBook Pro 13 2017 with no Touch Bar. I’m getting the classic “USB port drawing too much power. The device that is plugged into it will be deactivated” or something like that (My MacBook is Swedish). This problem occurs when trying to connect either a firewire interface using adapters, a Sandisk Extreme USB-C SSD or a Midi keyboard using Apple AV adapter. I’ve tried several times reseting NVRAM and SMCI’ve tried changing USBC cables.I’ve tried booting the computer with all the accessories already connected.I’ve tried connecting the Sandisk SSD to my Apple AV adapter with power connected to the adapter

Sadly, there is nothing you can do here as the logic board has a problem. You’ll need to get your system to someone with the needed deeper skills to toubleshoot and repair your logic board or you’ll need to replace it.
