Hi everyone,
My Razer Huntsman V2 Tenkeyless (USB ID 1532:026B, bcdDevice 1.01) has a lighting issue at every boot:
When I power on the computer, the keyboard lights up while the BIOS/manufacturer logo is shown.
At the exact moment the BIOS hands over to the operating system, the lighting turns off.
The keys keep working, but the lighting stays off until the computer sends a lighting command to the keyboard again (device mode / brightness / effect). Without that, it can stay dark indefinitely.
What I have tested:
- Plugging the keyboard in while the OS is already running: it lights up and stays lit.
- Plugging the keyboard in while in the BIOS setup screen: it lights up and stays lit.
- A Razer Pro Click V2 Vertical mouse on the same computer keeps its lighting during the whole boot.
- The darkening happens before any operating system driver or software is loaded, so it does not seem to depend on the OS (I use Linux).
Computer: ASUS VivoBook X415EA (BIOS X415EA.311), Intel USB controller, keyboard on a USB 2.0 port.
My understanding is that during the BIOS-to-OS handoff the USB bus is halted and reset, and the keyboard firmware does not restore its lighting afterwards, while other Razer devices do.
Is there a firmware update for the Huntsman V2 Tenkeyless that fixes this? A similar startup-lighting issue on the BlackWidow V4 Pro was solved with a firmware update.
Thanks!
