AC1) Manual test: When file cashing is turned on one should be able to list objects(`pkcs11-tool -O`) on card after the card is reinserted.

AC2) Optional: All manual tests from general testplan should pass when executed with new CardOS cards.

.OpenSC might not detect CardOS V5.3 card objects correctly

The OpenSC toolkit does not correctly read cache from different PKCS #15 file offsets used in some CardOS V5.3 cards. Consequently, OpenSC might not be able to list card objects and prevent using them from different applications.

To work around the problem, turn off file caching by setting the `use_file_caching = false` option in the `/etc/opensc.conf` file.

////
Future bug fix text:
File caching was not working correctly for some CardOS 5.3 cards that stored certificates on different offsets of a single PKCS#15 file.

The file caching was ignoring the offset part of the file, which caused repetitively overriding the cache and reading invalid data from file cache.

The issue was identified and fix upstream and CardOS 5.3 cards should continue to work well with file cache.

...snip...
The keys/certificates are instead in the path 3F 00 -> 20 00 and 20 01, which already points to DF D2 76 00 00 98 C0 00 00 and similar. In the trace, it is visible that the proprietary driver goes this path by default. I did not worked enough with the PKCS#15 cards to be able to put something working together or point you to the right direction what needs to be changed in OpenSC to make this working, but I think we will need some fallback in sc_pkcs15emu_cardos_init() when sc_pkcs15_bind_internal() fail to read the information from standard path. Probably by manually creating the DF structures to aid the standard PKCS#15 code to find the final keys/certificates. I have the annotated APDUs from the trace if you want to pursuit this challenge of getting your card working with OpenSC. I will probably not have much more time to do that now.

pkcs11-tool fails to list the card objects.
