I wonder if this is one of the cards/readers that can not handle

It looks like he is using the SCM SPR 532 [1]. This reader is limited
to an APDU of 260 bytes [2] (dwMaxCCIDMessageLength - 10) so only 255
bytes of data.
It is 1 byte less than the maximum.

You should only be able to get a 2040-bits length key with this reader. Too bad!
