Doing https://github.com/trezor/trezor-firmware/issues/435 beforehand would help us a lot.

We have agreed on with Product that we would like to keep the PIN entry on T1 as it is, that means using the pin matrix. Yes this has a drawback that the USB needs to be turned on beforehand, however we do not want introduce a new feature into the Port process.

This makes FIDO2 PIN entry on the device impossible. We could theoretically allow entering the FIDO PIN on host (FIDO allows us to specify this) - but this is a bad idea when the FIDO PIN will be the same as a device PIN (current situation) - introducing different PIN for FIDO also seems like a UX hell.

However, I guess we can live with FIDO being PIN-less on T1.
