Thunderbolt / USBC port only receives power, Not data.

[jrydinger]

Hey! I have a macbook pro 2017 with two thunderbolt ports. A problem arose a few weeks ago where only one port can receive data such as sound interface's via firewire to thunderbolt or a midi keyboard's USB2 to USBC. The lower (closest to my chest) port works as usual, but the upper one can only receive power. I have a case with apple customer support and combed the entire internet for info on this problem and now turn to apple support community. Is this something someone ever encountered? If so, what is the solution?

You might do a visual inspection of the port, to see if anything is "bent out of line".

Perhaps something called an "SMC reset" ??

The port look identical to the other(working) one and i've tried doing a SMC reset.
