Is there a simple fix to make my usb ports work again?
Neither of my two USB ports recognise anything I plug into them.
I have tries a pRAM reset and a SMC reset to no avail.
From time to time an internal warning sign pops up telling me to unplug USB (although nothing is physically connected) due to overloading. (I think the exact wording is "unplug device using too much power to enable USB")
I have had a look inside and I can see no damage, but I am a layman.
Can YOU see anything strange?
Is there anything I could tweak to get them working again?
