One out of two USB ports isn't working
I am very new to Ubuntu, so please excuse if this a trivial question.
I installed Ubuntu 12.10 64Bit successfully (after fighting a great amount of time with uefi and win8...) on my Sony Vaio SVT1312XES.
I managed everything to work except for the second USB port.
This is the situation:
I tested several pendrives, mices and other USB-equipment.
The working USB port, should be ready for USB 3, but i couldn't verify this because i don't own any USB 3 device.
But with USB 2 it works great.
I have no idea at all how to start to fix this issue.
I am very thankful for any help.
