[SOLVED] No YubiKey detected, even if usb device is recognized

I've installed yubikey according to Arch Wiki. The usb device is successfully recognized as FIDO2 security key. But ykman can't find the device. Any suggestions or ideas what the issue could be? I'm now searching for several hours, but got stuck so far.. Some relevant logs & diagnostics:

List of usb devices shows the FIDO2 Security Key:

$ cyme
  1   1  0x1d6b 0x0002 xHCI Host Controller 0000:00:0d.0 480.0 Mb/s
  2   1  0x1d6b 0x0003 xHCI Host Controller 0000:00:0d.0          -

  4   1  0x1d6b 0x0003 xHCI Host Controller 0000:00:14.0  10.0 Gb/s

The service pcscd.service is active:

Did you install yubico-authenticator-bin? Since the pcscd.service is active, maybe that is what is missing.

Re: [SOLVED] No YubiKey detected, even if usb device is recognized

It's a bit embarrassing. I have noticed that it is not a Yubikey but another manufacturer. Everything works now as expected!
Thank you very much for your help!
