SCARD_E_NO_READERS_AVAILABLE

SCARD_E_NO_READERS_AVAILABLE PC/SC cannot find an available smart-card reader. This may mean no reader is installed, the reader driver is not active, the Smart Card service is unavailable, or all discovered readers are unusable.

What to check

Call SCardListReaders to see the names visible to PC/SC instead of relying only on Device Manager.
Verify that the reader appears correctly in Device Manager and that its supported driver is installed.
If the reader is present but not usable, check Smart Card service state and reader-specific events.
