I am repairing a friends Macbook Pro Early 2011. The HDD had failed and they were desperate to retrieve photos.
I managed to do a deep scan on the HDD and recovered the photos to my NAS and I have just fitted a new Toshiba 500GB HDD.
I tried to install Mac OS High Sierra using a bootable USB device however the device was not recognised so I had to install Mac OS Lion using Internet Recovery.
Once I go Lion is running I have identified that neither of the two USB ports are recognising any of the three USB Thumb Drives I have.
I upgraded the OS to Sierra by downloading the OS from Apple and thought maybe that would do the trick but still no USB ports working.
I have reset the SMC (I believe this model has to use the non removable method) the power light is supposed to blink when doing this with the Shift / Alt / CMD and Power button held down but it did not? When I released the buttons the power light went green and then orange?
I have also tried reseting NVRAM by using the CMD Alt P / R and power on chime twice and then let it boot up. Still no USB ports?
I have just also tested a powered USB hub and the Thumb Drives connected still do not show up. This hub works on my own (newer) Macbook Pro.?
Anything else I can try?

Still have the overcurrent warning and no USB ports working?
