2 of my USB ports have only power but no data
2011 21.5” iMac (iMac12,1) with a i7 CPU and running macOS High Sierra (10.13.6)
I'm pretty stumped by this...
2 of my USB ports have stopped working, but not completely... if a flash drive is plugged in it'll briefly light up before turning back off and not showing up at all, USB devices which need a USB port to charge work fine but no external drives or devices, and the other 2 ports still work completely fine
What I've tried already:
- Restarting
- Resetting PRAM
- Resetting SMC
- Checking software update
- Reinstalling macOS
- Apple hardware test (hold D at startup) running the Extended apple hardware test
Please does anyone have a suggestion? thank you in advance
