HP Smartcard keyboard not working

I have an HP Skylab Smartcard keyboard and from what I can tell, the device itself is recognized by the system. It's just that when I try to test login it does not ask me for my PIN. Instead, it returns an error as shown below:

$ uname -a

Aborting.

For comparison, I have a different card reader that works fine:

$ pkcs11-tool --list-slots

This looks like some kind of config issue but I can't tell what. Does anyone know what CKR_FUNCTION_CANCELED means?

Turns out the issue is related to pinpad as described here: https://github.com/LudovicRousseau/CCID/pull/65
The solution, in my case, was to upgrade libccid to the latest version (1.5.0). I just downloaded a deb file from here and used dpkg to install it on my machine. The keycard reader is now working as expected.
