Hi guys, Both of my USB ports just stopped working this morning. If I plug anything in, I can still charge devices, but none of them will get recognised. Also, this morning I got a message, that some of my USB ports was drawing too much power and was disabled. At this point I connected the USB to the second port, which stopped working shortly after. I have done the smc and pram resets. It's a 2011 1.7GHz i5 model. Any ideas?
