And opening the notebook would probably void the warranty. The next thing you should do is collect a usbmon trace for bus 2 (see the instructions in Documentation/usb/usbmon.txt). Start the usbmon trace, then do: echo 2-1:1.0 >/sys/bus/usb/drivers/hub/unbind echo 2-1:1.0 >/sys/bus/usb/drivers/hub/bind and then stop the usbmon trace. Post what you get along with the dmesg log during this test.
