OpenWRT/TurrisOS + gnupg/Yubikey/smart card = NOPE

Currently I’m trying to debug why my Yubikey 5 and 4 are not detected in OpenSuse, so I was thinking - great, I have Turris Omnia, it has USB port, I’ll try it there. Well, not so fast. While OpenWRT is an universal operating system for routers, gpg or gpg2 there do not support smart cards. What now? I’m afraid this is the end of the road. I’ll boot live Ubuntu or something.

I installed these packages:

gnupg2
gnupg2-dirmngr
gnupg2-utils

And I get:

root@allie:~# gpg --card-status
gpg: invalid option "--card-status"

with dmesg:

[602686.517362] usb 4-1: new full-speed USB device number 2 using xhci-hcd

[604066.846442] usb 4-1: new full-speed USB device number 4 using xhci-hcd

While gpg in OpenSuse:

damon@rapthalia:~> gpg --card-status
gpg: selecting card failed: No such device
gpg: OpenPGP card not available: No such device

with dmesg:

That’s it.
