Frontmost USB port stopped working properly on a MacBook Pro 13" Late 2011 I bought my Macbook Pro new this year in Jan 2012; it is the 13" Core i5 SKU. The USB port furthest from the screen on the left does not work with storage devices, though I have tested it with a USB Mouse and it seems to work. However on hard drives, USB keys, and an Arduino it doesn't work.

I cannot sync my iPod touch with it either.

Does anyone know what this may be?
Just reset PRAM and it will start working again. It has done it for me many times.
