MacBook Pro Early 2011 Both USB Ports quit working
A few days after out of warranty both USB ports quit working.
Apple replaced the motherboard for a one time customer favor. The USB ports worked for a few days, then quit; they have not worked since.
I have tried clearing PRAM, SMC, reloading OS from scratch, cleaning the ports with Isopropyl alcohol with no luck.
I never received the over power notice and the only things that have been put in them are a mouse, usb hard drive for time machine, and thumb drives.
The only thing I have found are the fuses might be blown but a new mb is 1,000 plus.
Really do not use it and would like to sell it, but with the USB ports not working, I think that will prohibit it's selling.
Any ideas would be appreciated.
