USB Ports not working

Hello,

So I have problem on my Mac with usb ports. First USB port(left one on the side) doesn’t work at all, it doesn’t give any signal. Another USB port is barely working. With external hard drive in it it shows me error “usb accessories disabled - unplug the accessory using too much power to re-enable usb devices” but hard drive is spinning and lightning.

When I plug my phone, it starts charging it but not showing up on desktop. Tried few USB sticks but still not showing up.

I was googleing a lot, did the SMC and NVRAM reset and still the same, looks like a hardware issue.

I want to know which part exactly needs replacing and where can I get that part because changing logic board is too expensive, doesn’t worth it for this old mac but it’s still i7 and holding strong.

Answer this question I have this problem too

Is this a good question?
