Supported values of WHAT are:
socket_name - Return the name of the socket.
status - Return the status of the current slot (in the future, may
also return the status of all slots). The status is a list of
one-character flags. The following flags are currently defined:
'u' Usable card present. This is the normal state during operation.
'r' Card removed. A reset is necessary.
These flags are exclusive.
reader_list - Return a list of detected card readers. Does
currently only work with the internal CCID driver.
