If you have the contact of the reader vendor, you can request a checked-build driver (which outputs debug messages). When the Windows session is unlocked, you would probably see the driver sunk into certain infinite loop around read FIFO or something. It usually has been the main reason SCardGetStatusChange not returns.

Of course there might be other reasons such as a third-party smartcard security application running when workstation session is locked and it uses poor method to poll card present status thus it exclusively locks the reader resource ...

Basically you can figure out most situations by reading the driver logs.
