D.K.

I'm facing the same "EF offset too large" error when trying to create PKCS15 structure. Hardware: Macbook with Apple Silicon OS: MacOS Monterey OpenSC version: OpenSC-0.22.0-rc1-74-gc902e199, rev: c902e199, commit-time: 2021-08-10...

@FeitianSmartcardReader yes this is ePass2003 USB token from 2015, e.g. 7 years old I will post PID later today when reach macbook.

@FeitianSmartcardReader OpenSC version mentioned above in original message, e.g. `OpenSC version: OpenSC-0.22.0-rc1-74-gc902e199, rev: c902e19, commit-time: 2021-08-10 11:09:03 +0200` Unfortunately linux is not easy available without searching for some virtual image...

Some test results for commands Works in 0.22 but not in 0.20 ``` pkcs15-init -E ``` Works in 0.20 but not in 0.22 ``` pkcs15-init --create-pkcs15 --profile pkcs15+onepin --use-default-transport-key ```...

Update: With OpenSC 0.21 (previous version) both commands `pkcs15-init -E` and `pkcs15-init --create-pkcs15 --profile pkcs15+onepin` works Initialising of pkcs15 structure with default options (incl SO PIN and PUK) not working...
