What is strange is the response RDR_to_PC_SlotStatus (first byte 81h) when a card is present and powered.
The normal CCID frame should be:
81 00 00 00 00 00 xx _00_ 00 00
00 is: An ICC is present and active (power is on and stable, RST is inactive)

But in the case of the HP we have:
81 00 00 00 00 00 xx _01_ 00 01
01 is: An ICC is present and inactive (not activated or shut down by hardware error)
The last 01 is: Clock stopped in state L

Something (the reader? the BIOS?) decided to stop the reader clock.

I need more information about your Alcor Micro reader.

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.
