MacBook USB ports not working, reading? or recognized? Try an SMC + PRAM Reset to solve this problem.
MacBook USB port not working properly? or won't recognize any USB devices? Seems like there is a bunch of people who are having USB ports issues in MacBook Pro or Air. Don't worry anymore, Here is a way to solve this issue. We are going to reset the SMC and the PRAM to fix this issues. SMC stands for Resetting the System Management Controller and if there is a collision on the system management controller, your MacBook might not be worked properly. Also you can reset the SMC + PRAM whenever you have one of the following symptoms:
The System report states 'Thunderbolt: No hardware was found.' The thunderbolt ports were last recognized by 10.10.3. I did SMC and PRAM. Self diagnose test passed at least twice. The third time running it (at the request from Apple support) the cooling fan in iMac spinning crazy. I aborted the test. Not sure this is problem or not. The problem could be related to a technical issue – maybe a damaged USB port on your camera or on the computer. To troubleshoot this, you could try plugging the USB cable into another port on your computer. Or try another USB cable. But to access your photos quickly, I recommend removing the memory card and using either a card reader or adapter. Unplug the USB stick from the current port and computer, and try plugging into a different computer and/or USB port. If it works on the new USB port or computer, the USB port may be damaged or dead, or the computer itself may have a problem. This article also includes a workaround that you can try if these methods do not work. Method 1: Use Device Manager to scan for hardware changes Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.
