A: Yes, the driver passes APDUs transparently. For DESFire EV3, ensure your driver version is v2.0 or newer.

| Issue | Likely Cause | Solution | |-------|--------------|----------| | Token not detected | Conflicting driver (e.g., Microsoft generic CCID) | Remove old driver via Device Manager → Uninstall device → Delete driver | | “Smart card not recognized” in Windows | Minidriver not registered | Reinstall with Admin rights; check certmgr.msc → Smart Card Certificates | | PIN pad not working | Missing vendor middleware | Install TokenME Management Utility | | Error 0x8010002e (No smart card reader) | PC/SC service not running | services.msc → Smart Card → Startup Automatic + Start | | Linux: pcsc_scan shows “Unknown card” | Missing ATR entry in libccid | Update libccid or add custom ATR to /etc/opensc.conf |

Most TokenME devices come with management software that installs the drivers automatically.

  • Concurrency limits
  • Caching
  • Monitoring 
    • # Install PC/SC tools and CCID driver
brew install pcsc-lite ccid
