Yes sorry, I know that it does not make sense. It was just to show that changing it will remove the Ethernet device again and I can not use the Ethernet connection in HID mode then (unless I have a loop that waits for the Ethernet connection to be available).
I was not sure if this is an issue with just Windows 10 or if every version of Windows is affected. I think there are devices that work with RNDIS and HID at the same time in Windows 10, so it must be possible somehow. The question for me was just, how it can be done. I have a working code now but I thought this is not the best way to do it as it creates delays and officially the bunny should be able to do that. Maybe someone else had it figured out but it doesn't look like.
Thanks all for your comments.
