I don't think so. I think usb-c based phones don't need any type of active adapter.

For example, on usb-c iphones, I can plug my camera with a c-to-c cable in mass storage mode and it shows up. So I expect a dumb a-to-c adapter would work. On my lightning-based iphone, a c-to-lightning cable doesn't work.

I'd assume it's the same for androids and keyboards.
