I have the same problem, using pcscd 1.8.14-1ubuntu1.16.04.1 on an IBM Thinkpad P50, which has the same card reader.
However, interestingly, it only happens when I use a Feitian/Entersafe A22CR card. I tried two of them with the same result, so it's not a flaky card either. When I use a PIVKey C910 card, it does not "flap" like it does with the entersafe card. The PIVKey card works fine in the reader. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307109 Title: Alcor Micro AU9540 keeps powering down when card is present To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcsc-lite/+bug/1307109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
