The patched kernel works for me. USB 3.0 ports are working fine now. I did, however, observe that when the flash drive was plugged in to HighSpeed USB ports, xhci driver was always used for one port and ehci for the other, as if the HighSpeed port is actually working in SuperSpeed mode. It is a good thing for me :). The system is a Lenovo ThinkPad E430. Either way I am glad that I don't have to go through a suspend-resume cycle to get USB 3.0 ports working. I've attached the file which contains the dmesg snip.
