Thank you very much.
FYI, despite installing scdaemon, I see the following:
Try rebooting, or restarting scdaemon. There’s a possibility that the package doesn’t automatically start the scdaemon service.
There is no service:
~ dpkg -L scdaemon

/usr/share/metainfo/org.gnupg.scdaemon.metainfo.xmlUdev itself may possibly need to be restarted. But first before you reboot, try removing and re-inserting the Librem Key to see if udev picks it up.
Are you using PureOS? On a brand new vanilla PureOS install here, I just had to install scdaemon, then reinserted the card and gpg --card-status worked. No restarting services or rebooting.
Yes Sir. PureOS here all the way.
Login to your desktop, insert the Librem Key and then run gpg --card-status.
That video was of dmidecode for some reason, maybe you meant to paste a different video. Please try logging in as your regular user, inserting the Librem Key, and running gpg --card-status. It should just work, as the only additional package you should need is scdaemon, which you have installed.
Right, I wanted to show you the output of dmidecode so you could see I am running PureOS, etc. but I really should have just shown you my /etc/apt/sources.list or something 
In any case, I’ve gone through all these steps and continue to see the original error. Reading through gpgconf’s man page, I learned about its --check-programs arg and see everything is available and working.
~ gpgconf --check-programs

I can also reproduce the original error across both USB ports (had to try). Really not sure what other knobs to turn here. I happen to be using gpg 2.2.11. Can I ask your version?
I’m using the default gpg 2.2.11 package with the default terminal and shell on the default PureOS desktop. On this side I took a Librem 15v3, installed a vanilla PureOS on top of it and then installed scdaemon and the Librem Key showed up with gpg --card-status.
Got it! Found disable-scdaemon in my ~/.gnupg/gpg-agent.conf
duh
@Kyle_Rankin Hi ! will the Librem Key work only for the Librem laptops or will it also support the Librem 5 once it gets released ?
My apologies if this has been asked before, but could a future version of the Librem Key be in a similar form factor as the YubiKey NEO, and not like a standard USB drive? It seems to be much more durable that way.
A USB-C type would be awesome and much more usable than the USB-A Version it is now.
The goal is to support the Librem 5 as well, but because the Librem 5 has a USB-C connector, it means using a hub or other adapter to use existing Librem Keys. At some point we would like to offer a USB-C connector option as well.
Also note that the Librem 5 will feature its own internal OpenPGP smartcard reader so it can already perform a lot of the security features of the Librem Key with respect to secure key storage.

github will require 2FA at the end of the year, so I guess I will need to get something other than a Librem Key.
Or, stop using GitHub to begin with.
