A:
I would imagine, that once you have a USB type c male to USB type A female adapter, that should work.
My wife just unboxed her iPad pro, gen 2, but I don't have the adapter to verify, whether it works. The adapter is just a few bucks, it's probably worth testing it out.
There is another option. If you like the trackball action, the MX Ergo ( $99) has Bluetooth capability.
Hope that helps.
