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.
