USB 3.0 Only Recognizes External Drive no Other Devices
I have a MacBook Pro 15.4" - Mid 2012, Model #A1286, 2.6GHz Core i7, running Mac High Sierra, 10.13.4. The USB 3.0 Ports will only recognize an external hardrive and no other device. I have tried using a powered USB hub for other devices and it will still not recognize the devices. I have reset the PRAM and the SMC. (Version 2.1f175)
Any help is appreciated.
