macbook had a recent chip replacement, as it was fried due to overheating. now that everything "works" (as in, it boots), i am unable to use the usb ports.
read through pretty much most of the related posts here from the last 6 months, and tried most of the suggestions.
these usb devices work fine on other computers.
observations -
1. when optical mouse is connected, it is unresponsive, but it has a lower intensity and consistent blink.
2. no light indicator when a flash drive is connected.
3. neither devices showed up in the system profiler or anywhere.
can someone help?
