Are you plugging it into a USB Hub? Try a different USB port that is directly on the computer, and also install Synapse 2, not 3. I've not had any issues with my mano'war's since i bought them a while back.
@pdoherty is correct, hey
@motis90 , you should try the customisation for mano'war via the previous gen Synapse "synapse 2.0" and not the "3.0".
Also if changing usb port doesn't resolve the issue, can you also try the below steps as it works on my computer when it faces the usb error.
- Select Start, then type device manager in the Search box, and then select Device Manager. -Expand Universal Serial Bus controllers. Press and hold (or right-click) a device and select Uninstall.
- For the usb where it shows dongle connect or for each device.
- Once complete, restart your computer. Your USB controllers will automatically install.
