Antwoord op "MacBook Pro doesnt charge / connect to iPhone 11"Ok so for anybody else with the same issue (USB3 devices work, USB2 don’t or are intermittent). Connecting a powered USB3 hub to either USB port then allows me to connect USB2 devices (iPhone) to the hub and for them to charge and sync as normal. This indicates a likely power issue - have obtained a copy of the schematic for the Macbook and looked at the USB ports I can see that the power to the USB sockets for USB2 is controlled by U4600 which is a TPS2561DR. This seems like the most feasible cause. Also various Google searches back this up as it seems a part that is often replaced. I am fortunate that I work for a company that produce electronic equipment (I write software) so they have all of the necessary facilities to remove and replace the chip (which is only £1.90!) - so that’s my long term plan - but will do that once I clear current work load!
