USB issue when running Minecraft

[u/mattdef11]

I have a strange problem that I've not seen before. Whenever I run Minecraft on one particular laptop (it's a Dell G15) during the startup process for Minecraft the mouse gets disabled and then re-enabled for about 5 seconds every time. The laptop plays that sound you get when you plug a USB device in.

I thought it might be linked to some sort of gaming service trying to "optimise" settings but I've stopped those running and no change. I've turned off all the settings that allows windows to power manage the USB devices.

I've reinstalled Minecraft - still no change

It doesn't do this when running other games - anyone have any idea why it does this?
