Welcome to the Club,
OK your drivers have gone south but don't panic. Go to the vaio Link and download the drivers bundle which is about 32 meg. However try this first.
Right Click on My computer go to Properties>hardware>device manager>and in the tree links navigate to the usb hub. If there are explaination marks next to it go into them by right clicking and delete the driver and restart. The will restore the correct driver automatically. If not then you have deleted your recovery partition so you will need to replace the drivers at Vaio Link download and follow the above directions with all devices that are errant. Good luck:smileyhappy:
