One usb port works, second does not. This is the second unit like this
This is the second unit I’ve rebuilt that has one good usb port, and one that has power only, no data. I tried SMC and NVRAM. Nothing seems to happen during the SMC reset. The power cable does not blink, or anything similar, as described in the process. Not sure what to do, aside from supplying a USB bank with the unit. Why would it supply power and not data? Nothing is recognized, from a mouse to a Flash Drive. But it will supply power to a usb light. Any ideas appreciated. I also tried just holding the power button down without any power connected. Currently, there is no battery in the unit.
Is this a good question?
