app-openpgp: Ledger Nano S not detected by GnuPG

Hi,

I tried to set up my Ledger Nano S for GnuPG, but I cannot detect the Ledger as a smartcard reader on MacOS Catalina (10.15.7):

# gpg --card-edit

gpg: selecting card failed: Operation not supported by device
gpg: OpenPGP card not available: Operation not supported by device

similarly:

# opensc-tool -l
No smart card readers found.

Ledger seems to be already present in libccid bundle:

cat /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist | grep Ledger
		<string>Ledger Nano S</string>
		<string>Ledger Nano X</string>
cat /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist | grep '0x2C97'
		<string>0x2C97</string>
		<string>0x2C97</string>

I have the OpenPGP.XL app installed on my Ledger (installed via Ledger Manager).

Any ideas?
