Razer Viper V2 Pro USB Dongle Not Recognized by Windows (Device Manager Shows Nothing)

Hi all,

I'm having an issue with my Razer Viper V2 Pro where the USB dongle is completely 
unrecognized by Windows.

**My situation:**
- Wired connection works perfectly fine
- The dongle shows nothing in Device Manager when plugged in
- No LED activity on the dongle
- Tried multiple USB ports (including rear motherboard ports, USB 2.0)
- Tried on a different PC — same result, not recognized

**What I've already tried:**
- Different USB ports (front/rear, USB 2.0 and 3.0)
- Reinstalled Razer Synapse
- Re-pairing via the button on the mouse bottom
- Tested on another PC

The dongle itself seems to be dead. Has anyone experienced this?
Did Razer support send a replacement dongle, or did they replace the whole unit?

Any help appreciated!

Hi ​@tomokin966,

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