These events are generated by scardsvr and smclib (on behalf of the
drivers) on failure to power the "non card".
By design, the resource manager wants to know what kind of card was
inserted in the reader and will try to power it up.

Subject: Error events in "System Event Log" on Win2K when user inserts a
Hi people in this group,
I found that there are several error events generated in "System Event
Log" on Win2K when user inserts a non-smart-card. These error events
also happen when you execute SCardDisconnect() function to disconnect a
non-smart-card in the reader though it returns SCARD_S_SUCCESS. We have
tested 2 PC/SC readers (certified by Microsoft) and both have the same
error events. One company told me it should come from Scardsvr.exe
(smart card service) not from reader's driver.
Our company made a reader that use direct control to read/write
synchronous cards so there is a need to insert a non-smart-card. Even
for a smart card reader, user may insert a wrong card or form the wrong
side. Although the Win32 API program works well, it troubles us so many
error events keep generated.
Does anyone here also care this problem? Any suggestion is welcome. Hope
that the people in Microsoft would care.
