I am unable to install the driver for the above adapter. The initial reason is that it fails the driver signature test required for 64-bit drivers. I have attempted to disable this checking in the BCD (using VistaBootPro) but it does not seem to make any difference.

(Does this only work for Vista 64-bit?) Device Manager properties for the device indicate 'Windows cannot verify the digital signature for the drivers required for this device.' I use this device to connect my GolfLogix GPS Rangefinder. I would like to be able to test the device (before the golf season starts in Canada!!!) but am unable to right now.

Are there any work arounds to allow the driver to install? I have tried Vista compatibility mode, but it makes no difference. The driver appears to install, but attaching the cable results in failure of the drivers to load.
