I've had a bit of (mis)experience with this myself. I have been able
to use the extended APDU with OmniKey on GNU/Linux, but only using
their proprietary module (that's with pcscd).

As a side-note, one more thing is that very often (99% of the time) the
contactless interfaces on lots of readers won't work with CCID, and
require proprietary drivers (OmniKey included).
