Quick update to say my Digitone is working fine with Overbridge now thanks to Patrik at Elektron. Copying and pasting the solution here for anyone else that might encounter this issue. 
- Power off the Elektron device and disconnect it from the computer.
- Go to Windows Device Manager.
- Expand every category.
- Go to the top View menu and press on Show hidden devices.
- Where you see the Elektron device, right-click and press Uninstall device.
- Connect the Elektron device to your computer and power it on.
