Hopefully it’s just a firmware fix and not an issue with the usb controller chip.SAN DIEGO- (January 3, 2018)- Due to the growing excitement and love of quick charging, USB Power Delivery (USB PD) and its capabilities have become highly talked about in the tech world. You seem to have a case of ‘Apple Derangement Syndrome.’ From what I’ve read in the article, this is a problem with the MacBook until proven otherwise. Therefore they have bad firmware? And the included ‘problem’ devices include Apple keyboards. So the devices worked before and work with other computers but suddenly stop working with the MacBook. In the meantime, of course, this new 'USB-gate' will grow legs, become a viral 'thing' on tech blogs, spawn class-actions, and turn Apple into a punching bag once again.

Oh the outrage, the claims of skullduggery by Apple to force people to buy only Apple RAM. Look, this could indeed be a problem with the Macs involved but travel down memory lane with me to the time when an OS X update caused cheap, third party RAM to stop being recognized. Of course the firmware of these USB 2 devices are perfect and flawless, right.
