Keyboard G815 usb pass-through doesn't work

Hi u/Dyrdin-op,

Try the below steps and check if it helps fix the issue:

- Connect both of the USB plugs to working ports on your PC

- Try connecting different devices to the passthrough

- Update the device's firmware

  1. Download and install Logitech G-Hub (Available here:

  2. Launch the software, select the keyboard from the home screen then go to Settings

  3. If a firmware update is available, a Blue "Update" button would appear under the firmware version on the top right corner of the screen

- Test on another computer and check if the issue persists.
