No, it's not needed to search up.  ATTR is OK for our use case of
scdaemon.  We can assume that Yubikey supports CCID interface.

Please note that a single Yubikey device supports multiple interfaces.

My guess is that the entries are originally written with its interface
(ATTR{bInterfaceClass}==11 to distinguish CCID device).  That is, the
original entries are specifically for device with CCID interface.

We don't need that.
