--- Comment #7 from Damien Miller <djm at mindrot.org> ---
No, ssh-keygen doesn't cache anything. The persistent failure could be
explained by the USB bus getting confused or something hogging it.

I think the next thing to try is to put libfido2 in debugging mode. It
might be possible to do this by setting the FIDO_DEBUG environment
variable, but it's also possible to do it by editing sk-usbhid.c in the
OpenSSH source and uncommenting the "/* #define SK_DEBUG 1 */" line.
