The Lighting Controller II

Also USB OTG would be nice for old Android tablets. So existing dongles can be used. I think users who like this setup eventialy will buy the wireless dongle.

Sorry but we do not see any interest to use USB with a mobile device.
Laptop computers do that well.

Lightrider is doing this for years and a lot of users start with a old tablet, a wired dongle and a usb OTG adapter before they purchase thier wireless dongle. I do not need this function myself, just was wondering if this would boost sales eventualy. Maybe not because it is not the same target group.
