DG40S WORKED with Bluesoleil driver BEFORE but suddenly stopped working
If your DG40S worked with Bluesoleil driver before but stopped working once your computer updated, please go to device manager. If there shows "Bluesoleil Generic Bluetooth driver", please uninstall it. And then reboot the computer with DG40S plugged in. Now you can use the DG40S directly, no need to use the Bluesoleil driver.
