It may be possible to make the driver work with this reader.
I am not sure how to come back from the state An ICC is present and inactive.
Without such a reader at hand it will be hard to debug the driver.
Maybe you can offer me a Hewlett-Packard HP EliteBook Folio 1040 G1? :-)

alternative Control USB bytes we need to send? Or do we think this
failure is because of something else (reader clock being stopped.)

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
Your reader firmware is newer than the one I have at

Maybe you can find a reader firmware update from Alcor Micro or HP.

OK, in comments #22 and #23, we have outputs with ccid compiled with the
patch to add some more debug in #24.
Comment #22 features a working Lenovo laptop.
Comment #23 features the HP laptop.
For some reason, the HP laptop hits the IFDHICCPresence() function's
CCID_ICC_PRESENT_INACTIVE case and
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:

That output above is what happens without touching the card or running
an application - it just sits there with Card present, as soon as I do
something like 'opensc-tool -l' - the card is absent and then it
eventually loops back to present.

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.

Why does powering down a present card is a problem?
A problem would be if the reader reports no card inserted when a card is
inserted. Is that what happens?

Ludovic: That is exactly what happens. I'm not touching the card and as
shown in comment #3, it keeps appearing and disappearing.

Please generates a pcscd log as in #2 but without starting any
application. Just insert a smart card and wait.
