GSP 670 - Troubleshooting the dongle connection
Please follow these steps:
1. Try to insert the dongle to other USB ports. If it is connected via unsupported third-party devices such as USB hubs, docking stations or port replicators, try to insert the dongle directly to your motherboard.
2. Make sure that your dongle, your GSP 670 headset and the EPOS Gaming Suite software are all up to date.
3. If you have any other audio software installed, please uninstall and try again as some might interfere with sound.
4. Go to Device Manager and right-click on the dongle, and try to perform uninstall/re-install the driver.
