The USB Gecko uses an FTDI chip (I believe it is the FT 245R (http://www.ftdichip.com/Products/ICs/FT245R.htm), a USB FIFO).
Windows Update does not usually have the latest driver. The latest FTDI drivers are available from the manufacturer's website. http://www.ftdichip.com/Drivers/D2XX.htm
As of this posting, 2.08.17 Beta Version (http://www.ftdichip.com/Drivers/CDM/Beta/CDM20817.zip) is the latest release.
