Document the need to add a config file to disable gpg scdaemon internal CCID driver and use pcsc for pico-openpgp (and pico-fido2)

[Lab-8916100448256]

As per discussion on discord :

Have you used the pico-openpgp firmware?
I tried to use it with gpg but all I get is

$ gpg --card-status
gpg: selecting card failed: No such device

No I have not, I was actually going to flash pico-fido2 first, but PH closed sourced it, so I just gave up on openpgp part. I kept openpgp and hsm for later, after picoforge implementation completely works with pico-fido.
I will setup a github project later, to track ongoing issues, planned features and features currently being worked on.
@onegrit have u tried picoopenpgp or picohsm?

gpg --card-status is working on macOS, using Yubico VID:PID (1050:0407)
It must be something missing or not configured correctly on my linux system.
Or it is not working at all under Linux.
If anybody could test on Linux to confirm that would be nice.

Nevermind, I found what was missing. I needed to add a config file to disable gpg scdaemon internal CCID driver and use pcsc :

$ cat ~/.gnupg/scdaemon.conf
disable-ccid
