Razer Basilisk V3 X HyperSpeed - Intermittent Disconnects with 2.4GHz USB Dongle

Hello Razer Support,

I am experiencing an issue with my Razer Basilisk V3 X HyperSpeed when using the 2.4GHz HyperSpeed USB dongle.

The mouse randomly disconnects or becomes unresponsive for about 1–2 seconds, then reconnects automatically. During this time, the cursor freezes and I cannot move or click.

I am using an Acer Nitro V 15 (ANV15-51-50UV) laptop, which only has USB 3.2 Gen 1 Type-A ports. Therefore, I am unable to test the mouse with a USB 2.0 port.

I have already tried the following troubleshooting steps:

  • Replaced the battery with a new one.
  • Tested all available USB 3.2 ports on my laptop.
  • Moved the dongle closer to the mouse.
  • Disabled USB power saving in Windows.
  • Updated Razer Synapse and checked for firmware updates (if applicable).

The issue only occurs when using the HyperSpeed USB dongle. Could this be a hardware issue with the dongle or the mouse itself? Are there any additional troubleshooting steps I should try, or would this be covered under warranty?

Thank you for your assistance.

When mouse stops working - do you hear hardware disconnect/connect sound in OS?

If yes, dongle may be faulty, so if you still have valid warranty, I’d just RMA it.

    While I am playing a game, the mouse suddenly loses connection and completely stops responding. I cannot move the cursor or click anything.

    At the same time, the green LED indicator on the mouse lights up, just like when I first turn the mouse on. After about 1–2 seconds, it reconnects automatically and starts working again.

    I do not hear any Windows USB disconnect/connect sound when this happens.

    I’d also try it on another PC to fully verify if it’s the dongle issue.

    Since you don’t hear any connect/disconnect device sound, it may be some RF interference from the other devices, so be sure it’s away from any power cables, other USB 3.0 devices (that also can do some interference), BT devices or other that works on 2.4GHz.
