USB port issue. Some devices doesn't work

Block Image

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

Lets see if the onboard diagnostics finds something (it may not). Restart your system and press the D key. Did you get any errors?

Reference: Mac startup key combinations

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 在已经存在的问题里加入图片

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

Hello Dan. I've replace battery and USB problem still there. Also I dissembled IO board and cleaned contacts. I'll try to reset SMC again after full charge

@Виктор Авсарагов - If the I/O board USB port is the only one affected, I would replace the I/O cable as often this cable breaks down, otherwise the I/O board would be the next thing I would suspect. 15" MacBook Pro I/O Flex Cable (Top), Apple P/N 076-1454 and 15" MacBook Pro I/O Board Coax Cable (Bottom), Apple P/N923-0666

If logic board USB port is also failing that points to a logic board problem within it.
