Is there a way to specify which smartcard reader to use?

[Alphazo]

Hello,

I have two USB dongle plugged in at the same time. One is the crypto
stick (OpenPGP card 2.0 + CCID reader) and the other one is a PKCS#11
token. I don't use any udev rule for the crypto stick as the latest ccid
lib supports it out of the box. Now I'm unable to do a gpg --card-status
with both token inserted.

gpg: detected reader `Feitian SCR301 00 00'
gpg: detected reader `German Privacy Foundation Crypto Stick v1.2 01 00'
Insérez la carte et tapez entrée ou entrez 'c' pour annuler:

Is there a way to specify which reader to use for that command?

For information, pcsc_scan reports the two readers correctly:
