YubiKey does not work at Firefox in snap

[Martin Venuš]

I have upgraded Ubuntu 21.04 to Ubuntu 21.10 beta. After upgrade I cannot use YubiKey at Firefox (probably due to snap). My expectation was that I would be able to use Firefox as before moving to snap.

Can you please run the following command in a terminal and share the output?

    snap connections firefox | grep u2f

Can you also share the output of `lsusb` ?

snap connections firefox | grep u2f
u2f-devices firefox:u2f-devices :u2f-devices

It looks like the relevant line is:

    Bus 002 Device 012: ID 32a3:3201 GoTrust Idem Key

This requires an addition to the u2f-devices interface. I submitted https://github.com/snapcore/snapd/pull/10848.
