BlackShark V2 HyperSpeed Dongle suddenly not recognized – Device Descriptor Request Failed

Hello Razer Support,

my Razer BlackShark V2 HyperSpeed USB dongle suddenly stopped working.

The headset itself was working normally before the issue occurred mid-game without any changes to my PC or the headset.

Windows detected the dongle in the Device Manager as:

“Unknown USB Device (Device Descriptor Request Failed)”

I have already tried the following troubleshooting steps:

  • Unplugging and reconnecting the dongle
  • Using different USB ports
  • Uninstalling the unknown USB device from Device Manager
  • Restarting the PC
  • Completely shutting down and restarting the PC
  • Testing the dongle on a second computer/laptop

The same problem occurred on both computers. Therefore, it does not appear to be a Windows-specific issue.

The Headset is working fine when I connect it via cable.

When I connect the dongle it shows a very feint green light for a second before going dark.

 

Could you please advise whether there is a way to reset/recover the dongle or if I can replace it?

 

Best regards

Hey ​@Seibotter,

It does seem that the wireless USB dongle is already defective. Can you send me a PM with the serial number of your headset together with your location/country so I can verify it in our system and check our inventory?
