Please consider adding onlykey support. Onlykey is the only open source hardware key out there.

Is this just about making the hwkeydriver detect the OnlyKey's USB product/vendor IDs?

The OnlyKey uses HMAC-SHA1 challenge/resposne just like a Yubikey does. And KeePassDX works with Yubikeys that way already, right?

Also I think the SoloKey is open source hardware.

What is needed to support OnlyKey? I've just tested my OnlyKey with KeePassDX and it seems to work fine.

More specifically:
I normally use YubiKey. I configured the HMAC key (slot 2) of the OnlyKey with the same HMAC key that is already stored in my YubiKey. Then I plugged the OnlyKey into my smartphone, entered PIN on the OnlyKey keypad and launched KeePassDX.

The only problem might be that Key Driver says "Press the button on your YubiKey." instead of "... OnlyKey." ;-)
