GetSlotInfo failed, CKR_DEVICE_ERROR

[Cobra00747]

I believe this is openSC however I don't actually know, I'm just running commands.

pkcs11-tool --module opensc-pkcs11.so --list-slots

Available slots:
Slot 0 (0x0): (GetSlotInfo failed, CKR_DEVICE_ERROR)

When I ran scan:

How do I resolve this?

I confirm your command does not involve libp11. It could be a software (OpenSC, pcsc-lite) issue, but the error message suggests a hardware problem with the token itself.

Thank you!

Where should I post this for help, I can't find OpenSC or pcsc discussion forums on here.
