Smart Card Events errors

Problem

When connecting a Regula device, you may encounter errors from the Smart Card Service in the Windows Event Log, most commonly with EVENT ID 610 as follows:

The smart card reader "%2" rejected IOCTL %3: %1. If this error persists, the smart card or reader may not be functioning correctly.%n%n Command header: %4

Where:

%1 — Windows error code

%2 — Smart card reader device name

%3 — IOCTL request sent

%4 — First 4 bytes of the command sent to the smart card

Solution

This event is caused by obsolete functions within the smart card stack and can safely be ignored if no noticeable issues occur during smart card operations.
