Thanks a lot, Hasu! Much appreciated 🙏.
I wasn't notified about your reply on this topic for some reason.

DirtyGingy:
I know these hit 1up keyboards a few years back, are they ever coming back?

Hello and thanks, the Insignia Wireless Ergonomic keyboard works.

I'm trying the converter on the keymouse (https://keymouse.com/), but it doesn't work, which I knew was very likely since there is no mouse support.

It also seems, the keymouse isn't 'boot' protocol.
