Diagnostics Tool: After installation, search your Start menu for EZUSB Diagnostics. This utility can test if the reader is communicating with your smart card correctly.

Windows Update: Sometimes Windows 11 can find a basic driver automatically. Go to Settings > Windows Update > Advanced options > Optional updates to see if a "Castles Technology" driver is waiting there.
