Hello, I've added a firmware for a gamepad

[Felixoid]

Besides the fact, that sudo fwupdmgr get-devices --show-all-devices doesn't work unless the gamepad in bootloader mode, it's in a better state now

[hughsie]

I'd really like someone from 8bitdo to be doing this work. If anyone wants to volunteer to manage the updates on the LVFS I can write to them and ask if this is acceptable.

[rhansen]

What do you mean by "manage the updates"? Do you mean create pull requests like this one on behalf of 8bitdo whenever there is a new firmware release? If so, I'm willing to do that.

[hughsie]

It's more the "Upload to the LVFS" bit I'm trying to avoid doing.

[rhansen]

I'm willing to do that as well.

[rhansen]

I believe you will also have to add an entry for the SN30 GP to https://github.com/fwupd/fwupd/blob/master/plugins/ebitdo/ebitdo.quirk before this will work.
