[Elecraft] USB-to-Serial cable

[Jim - KE8G]

Hi All,
I received a couple of cable from Elecraft today, and I am not having any luck getting them to work.  I go into the device manager and it says a driver has not been installed.  I tell it to update the driver, it goes out to the Internet, but returns nothing.  Any ideas?

Right now, I am trying to get it to work with my Toshiba laptop running Windows 8.

Thanks in advance,
Jim
