Razer Leviathan V2 X not detected in Synapse 3

I purchased the Razer Leviathan V2 X Pokemon Edition.

The soundbar is not detected through Synapse 3.0. The PC does not have a Type C port, I connect it via a Baseus USB Type-C to USB 3.0 Type-A adapter. Did not help.

How to make Synapse 3.0 see the soundbar? I reinstalled everything several times, to no avail.

It happens to me too, occasionally. I plug the usb cable on and off it solves it for a week or so.

I’m having the same issues with mine. Whenever I have to reset my PC the Sound bar starts acting up and doesn’t register with my PC. It turns on and the Bluetooth light just blinks, even when I connect Via bluetooth so sound comes out. 

 

Please help..

Anyone find a fix for this? I just got them recently and suddenly its disappeared.


I just received my Veciathan v2 Pikachu edition from china, and of course I have all the same issues described in this post, plus, I noticed that the soundbar works also without a power source! I means that it has an inner battery? But where? How? What capacity has it? I’m shocked, it is not displayed neighter said anwhere that it’s a battery powered device. I’m sad that I can’t control lights, effect, and EQ since Synapse doesn’t show anything connected. But I’m somehow happy to know that the device is portable, even if I don’t know how much battery and endurance it has. I'’ll try to test it out or maybe disassembly it and try to discover something more about that thing.

Hello. I have a Razer Leviathan V2 X Pokémon Edition, China packaging.Markings on the unit:

  • Razer Pokémon
  • RZ05-0428
  • RZ05-04280200
  • S/N 332302B04701979
  • CMIIT ID 2022DJ4129

Windows plays audio and shows the name “Razer Leviathan V2 X”, but the speaker does not enumerate as a Razer device.USB identity:

  • VID_4C4A&PID_4155, REV_0100
  • USB audio
  • HID consumer control
  • USB mass storage “BR25 UDISK”, no media

It never appears as VID_1532&PID_054A. Synapse 3 and Synapse 4.0.827 scan it and drop it. The only Razer USB device Synapse keeps is my Barracuda X, 1532:0536.I already ran CleanupRazerDrivers.exe, restarted the PC, and reinstalled Synapse 4. No change. The cleanup log lists the Barracuda only. This speaker is not in that list.Firmware:

  • The file offered for the registered product, Leviathan V2_FirmwareUpdater_v1.07.00.1043_r1.exe, is for RZ05-03920. It waits for a Bluetooth device named “Razer Leviathan V2” and USB 1532:0532. Next never becomes available.
  • Leviathan V2 X updater v1.07.01_r2 never enables Update. The speaker stays 4C4A:4155. “Actions USB 2.0 (HS) WinUSB Device” (VID_10D6) never appears. I tried several rear USB-C ports, a USB-A adapter, and different cables, connected directly, not through a hub.

Power:

  • After a full Windows shutdown the speaker stays on with its normal lighting. It is not the red power-off indication.
  • Other lighting on the PC turns off. The PC does not wake from USB. ErP Ready is enabled. Resume by USB Device (S4/S5) is disabled.
  • Unplugging the USB cable from the already shut down PC leaves the speaker on.
  • It then stays on for several hours on its own timer. Synapse cannot set that timer because it never detects the speaker.

Please confirm whether a genuine RZ05-04280200 must enumerate as 1532:054A, and what the repair or replacement path is when it stays VID_4C4A&PID_4155 and cannot be powered off from the PC.
