Windows: How to disable initial commands when card connect? #237

Closed Nick-The-Uncharted closed 1 year ago

Nick-The-Uncharted commented 1 year ago

Expected behaviour

Only reset command was sent to card.

Actual behaviour

A series of commands was sent to the virtual card. I searched project vpcd but can't found where did these commands came from.

Steps to reproduce

  1. start vpcd
  2. create a virtual card with VirtualICC(None, "iso7816", "localhost", 35963)
  3. run the virtual card

This is a Windows thing. Try this: https://learn.microsoft.com/en-us/windows/security/identity-protection/smart-cards/smart-card-group-policy-and-registry-settings#turn-on-smart-card-plug-and-play-service

@frankmorgner Thank you for your response, I set HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\ScPnP\EnableScPnP to 0 and rebooted, the commands received was less than before. If this is a system thing I guess will just leave that be.
