This is my target device because it is build-in in our Laptops,
i found this ct 2017-10 (german computer magazine) Article,
where they claim the reader to be working with the openpgp smartcard Version 2.1 
by transfering precreated 4096-Bit keys. This is exactly what i am tring to do - and it seems to work, only the stub keys are not being generated…

So either i am doing something stupid or the V3.3 card incorporated changes which broke this.
I ordered another reader and asked if it would be possible do buy some 2.1 cards for cross-tersting, but it seems they would have to be manufactured as they are out of stock.

Can anybody suggest how i could further debug the --card-edit and --card-status to find out why the stubs are not being generated?

Kind Regards,
