Razer BlackShark V2 HyperSpeed Dongle - Code 43 & "Device Descriptor Request Failed" (Cannot Update Firmware)

Hi everyone,

I am experiencing a persistent issue with the USB dongle for my Razer BlackShark V2 HyperSpeed. The headset itself seems fine, but the USB transceiver is constantly malfunctioning on my Windows desktop.

The Issue: When I plug in the dongle, Windows Device Manager does not recognize it properly. It shows up under Universal Serial Bus controllers as:

  • "Unknown USB Device (Device Descriptor Request Failed)"

  • "Unknown USB Device (Configuration Descriptor Request Failed)"

  • "Unknown USB Device (Set Address Failed)"

The device status shows Code 43 ("Windows has stopped this device because it has reported problems").

Symptoms:

  1. The dongle is not detected by Razer Synapse or the Razer Firmware Updater tool (the tool asks me to connect the device, even though it is plugged in).

  2. Occasionally, if I unplug/replug or re-pair it, it connects for a very short time but then disconnects and reverts to the "Unknown Device" error.

What I Have Tried So Far (Troubleshooting): To rule out software issues, I have tried the following steps without success:

  • Tested on a Mac: I plugged the dongle into a MacBook. It is not recognized there either, which leads me to believe this is a hardware/firmware issue with the dongle itself.

  • Driver Cleanup: I used Device Manager to "Uninstall Device" (checking the delete driver option) for all hidden/failed USB instances and rebooted.

  • Power Settings: I disabled "USB Selective Suspend" in Power Options and unchecked "Allow the computer to turn off this device" in USB Root Hub properties.

  • Ports: Tried multiple USB 2.0 and 3.0 ports directly on the motherboard (MSI PRO H610M-B).

  • Firmware Updater: I tried to run the Razer Firmware Updater, but since Windows doesn't recognize the device ID (VID/PID are failing), the software stays on the "Connect the dongle" screen.

Screenshots: I have attached screenshots of the Device Manager errors and the Firmware Updater stuck screen.

Has anyone managed to fix a bricked dongle like this, or is the hardware completely dead? Is there a way to "force" the firmware update when the device descriptor is failing?

Any help would be appreciated. Thanks!
