External keyboard not working at full disk encryption screen

General Discussion

Hi,

I have a laptop with qubes. All is working fine, qubes latest version.

I recently purchased an Onlykey and wanted to store my luks disk encryption password on it. Unfortunately the disk encryption input screen does not accept external keyboards! Onlykey shows up as an external keyboard to the laptop and it works just fine in qubes but it types nothing at the disk encryption screen.
Also tried with an external keyboard but same issue.

Is there a setting somewhere to enable usb keyboards at disk encryption screen?

Thanks

I’ve the same issue but I think it’s a feature, not a bug

I don’t really see why it isn’t allowed at the disk encryption screen. After logging into qubes you can set it to not allow usb keyboards without your explicit permission.

I think by default QubesOS does not allow USB connections, so rather than disallowing USB keyboards after logging in, you have to log in to allow them to connect from sys-usb to dom0.

However I could be wrong here

It is a security feature rather than a bug. Because it is trivial (and easy) to place an evil USB keyboard sniffing device between your USB-Keyboard and the USB-Controller and steal your disc encryption credentials.
