No reply from Renesas Europe yet, but I also contacted Sony, who have just replied..
Thank you for contacting Sony. We acknowledge that you would like to update your VAIO USB drivers but you cannot locate them.
The only available USB driver edition for your VAIO can be downloaded from the link below:
http://www.sony.ie/support/en/produc...1242-0042_6178
It is version 2.0.32.0, the other mentioned versions seems to be not available for this VAIO. So we would like to know if these are being installed by windows updates.
Um, are they trying to tell me that the Renesas USB on my 1 year old Vaio can not handle any further updates to the USB 3.0 driver??
