Please send full 'dmesg' output for this. That sounds like the card is
not in correct state after the initial primary firmware download.

No, it does not say such a thing and if it did, it would be wrong.
There's just one PDA in the card.

And what would would be the exact name of that firmware file?

I don't think so. I would be quite a bit surprised if the PDA were
somewhere else with your card since it happens to be in known location
for other DWL-650 rev E1 cards.

Yes, there can be; either with sreset after the initial firmware upgrade
or with the initialization after sreset.

Primary firmware should be in operational state at this point, so one
should be able to read its version and I think one of your prism2_srec
logs showed this already.
