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?


Solution 1:

Just reset PRAM and it will start working again. It has done it for me many times.
