IHello Steven, I try this procedure, but looks like the firmware reset is not done by the headset. I did not get any voice response from headset to reset the firmware. Bluetooth works fine, but I'm unable to pair the new USB dongle
Thanks for keeping me posted, Holger Bunkradt. That's unfortunate to know.
If that's the case, I'd suggest to reach out to our Microsoft assisted support at Contact Us Microsoft Support to diagnose the issue more. You might also need to get that USB dongle replaced again if necessary.
Nothing to worry, this particular concern is best handled by our live support. You can also contact them at Global Customer Service phone numbers (microsoft.com) underFor Business users. This also works with Home users, just select Surfacethen Homeas a type of user in the IVR prompt.
