Unfortunately I was aiming to use it to generate TOTP codes (and replace my authenticator app), but IIRC it needed a RT clock and thus a battery, which was not part of the design.
Great project though.
My low-level development expertise is pretty low, so perhaps there is a way, but after looking through the USB specification and other USB-development related docs, I just could not figure it out unfortunately.
The closest thing I found was to do someting like this (https://stackoverflow.com/questions/13335402/unable-to-sync-...) but I never did.
Do you think that would have worked?
