The readers report card present and then card absent. The driver can't
do much to know this is not correct and must trust the reader.

I will try to find a Alcor Micro AU9540 reader and to tests. But it
looks like it is a reader bug.

Title:
  Alcor Micro AU9540 keeps powering down when card is present

Status in “linux” package in Ubuntu:
  Confirmed
Status in “pcsc-lite” package in Ubuntu:
  Confirmed

Bug description:
  I have smart card reader built-into this laptop, however, whenever I
  insert a card - it'll read it for a few seconds, then the USB
  connection to the reader gets powered down and thus the card
  disappears in the systems eyes.

  After a few seconds, it comes back and everything's happy.

  Then the cycle repeats again and again and again.

  I think this is more a kernel issue than a pcscd one as, going by the
  logs, pcscd appears to be doing the right thing when the card
  disappears.
