This is the driver package for Odyssey
Drivers can be difficult to find and once they are found, can be tricky to install. Most drivers must be manually extracted, installed, and registered with the Windows registry. All drivers offered by DriverUpdate™ may be available free of charge from manufacturer websites. DriverUpdate™ costs $29.97 for a one-year license, which enables you to download any out-of-date drivers DriverUpdate™ finds.
Ugetfix_com needs to review the security of your connection before proceeding. Lastly, on your keyboard, you need to press the Windows key along with the I key to open Settings and see if the Bluetooth option is available now. If the device can be successfully removed this time, you can then switch back to the new Bluetooth receiver and pair your device again.
Hope This Works,
