Hi,

I applied the patch and the new debug output is attached.

And it works now as it should, without any devd(8) hook. I just start
pcsdd as a service via rc.conf and can attach or withdraw the security
token. When the token is not attached GnuPG asks me to insert it and
when it is inserted I'm asked for the PIN. All as it should be

A big THANKS!

Should I file a PR to get your patch included upstream?
