Openpgp card handling depending on manufacturer?

since i read that gpg2 now officially supports 4096 bit keys with the
openpgp cards i tested it with a different implementation of the card
and noticed something really strange. If i set the manufacturer field
of the card to 5 (Zeitcontrol) generating of a 4096 bit key using gpg2
--card-edit works as expected.
If i change only the manufacturer field to 1 or 2 (others i did not
test) generating stops after approximately 10 seconds with an timeout in
libusb_block_transfer (but only for 4096 bit keys, 3072 and lower works
Is there some code in gnupg that depends on the manufacturer of the card?
