I'm running pop_os 22.04 with gpg (GnuPG) 2.2.27

I have bought a HID OMNIKEY 3121 Smartcardreader.
When I run

gpg --card-status --expert

The output is:

gpg: selecting card failed: No such device
gpg: OpenPGP card not available: No such device

I tried to add disable-ccid in the ~/.gnupg/scdaemon.conf , but the problem persists.
With pcsc_scan the reader is recognized:

Using reader plug'n play mechanism
Scanning present readers...
0: HID Global OMNIKEY 3x21 Smart Card Reader [OMNIKEY 3x21 Smart Card Reader] 00 00

Mon Dec 18 18:11:34 2023
Reader 0: HID Global OMNIKEY 3x21 Smart Card Reader [OMNIKEY 3x21 Smart Card Reader] 00 00

Event number: 0
Card state: Card removed,

opensc also regognize the smartcard:

Detected readers (pcsc)
Nr. Card Features Name
0 No HID Global OMNIKEY 3x21 Smart Card Reader [OMNIKEY 3x21 Smart Card Reader] 00 00

The scdaemon log is as follows (debug-all):

When I search for this problem I mostly found only solutions for the yubikey/nitrokey, where it is recommended to disable the ccid.

I tried it also on a ubuntu 23.10 live usb and another Pop os machine, with the same results.

Edit: I've build gnupg 2.4.3 from the sources and looked at the problem at https://dev.gnupg.org/T6871.

when I run

echo scd getinfo reader_list | gpg-connect-agent --decode

I only get the USB Descriptor:

D 076B:3031:X:0
OK
