Ubuntu 7.04 with the distributed libpcsclite-1.3.3-1  and ccid-1.2.1ubuntu1
and Solaris 10 with compiled pcsc-lite-1.4.4 and ccid-1.3.0
both now do the extended ADPU with the PrimeCard and opensc-0.11.4-rc1


The issue appears to have been with the older versions of the ccid
driver distributed with the previous version of Ubuntu.

I think with the CCID there is some, but I don't know if PCSC
or OpenCT can pass that back to to OpenSC.
