Description

scdaemon is kind enough to fallback to PC/SC driver when the internal CCID driver is failed.
This is not that helpful, but invites confusion.

Once, PC/SC driver is loaded, the internal CCID driver cannot access readers/tokens, because PC/SC service grabs the access.

In 2.3, it's good to remove the fallback mechanism.

	rG100642e77696 scd: Remove fallback mechanism to PC/SC.

• gniibe changed the task status from Open to Testing.Mar 12 2020, 6:31 AM

• gniibe added a project: Restricted Project.

Making this task up to HIGH priority, so that people can easily find this change in 2.3.0.

For users who want to use PC/SC (on POSIX compatible OS, like GNU), now you need to have a single line in .gnupg/scdaemon.conf:
