I get following events from SCardSvr:
Reader removal monitor error retry threshold reached: The requested resource is in use.
AND
Reader monitor ‘USB Reader 2’ received uncaught error code: The requested resource is in use.
In which case does smartcard manager write these ? I have multislot reader and
this always happens with second slot. After that error, second slot (device) disappears from list of readers.
Regards
And how many readers have you tried? Do they ALL fail on slot 2? It does
happen that hardware does at times fail. If you haven’t tried more than one
reader you need to.

No, communication wise everything seems to be ok (there is no card in second slot, so driver does not even issue any communication on second slot). Just get_state, then for some reason 3 times? is_absent, then 2nd slot mysteriously disappears from list and event is given. Is there any kernel function to insert big delay, so I can see exactly after which request that event occurs ?
