Hi John, it seems the support for Windows* 8 is as-is. The DZ68BC is listed under discontinued boards.
I would try getting the device Hardware ID and searching for Windows* 8.1 drivers over the internet.
The Hardware ID can be obtained from Device Manager, double click the Motorola* wireless adapter, go to the Details tab, Select Hardware ID from the Property drop down menu.
I found a work around online, it basically creates a batch file that starts the Bluetooth program, and then I created an icon and pointed it to the batch file
works well enough for what I need it for.
thanks for responding
