+1. Nothing happens when you plug devices into the USB 2 port.

I've tried to check if there is any low level activity like usb interrupts or packet transmissions, and found nothing. Port is definitely powered. In preinstalled win8 this port worked fine, and in uefi bios it works too. Problem starts only during kernel boot process. May be usb controller initialization problem? I've checked latest stable kernel 3.9.6, problem is still there. Can you provide list with the information which will be useful to track the issue?

P.S. I've got Sony Vaio SVT1112S1 laptop.
