Hello everyone. I have problem with my USB on the right side of the laptop (HDMI, SD slot, USB) USB works well with external HDD, flash drives etc. It’s powers it and receive data. But if I plug any phone - it makes only charging. My midi controllers gets only power and doesn’t receive any messages. Also with wireless mouse. I checked I/O board - it’s ok I’ve replaced I/O board cable - it’s brand new and problem still not solved. I’ve reset SMC and NVRAM. All cables are fine and works well in other USB slot straight and with power USB Hub Please help with solution
Given the systems age needing a new battery does make sense. Lets get a some more on the batteries condition as it can effect how your system is working. Install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see Adding images to an existing question The power management logic (SMC) will cut off power to the USB ports when they’re too big a drain. I would see what they are delivering for power using a USB power meter like this USB Mini Voltmeter
