Weird, are you sure that it is failing in one of those checks? It
never happened to me before, you just switch dongle, right?

Make sure you did paired with device before attempting to connect, you
can also mark it as trusted so it does ask for confirmation, if it
still fail could you please send us the hcidump and bluetooth output?

Nope, you are correct, the hardware should not affect much the
profiles, of course profiles depending on things like SCO may be
affected by the hardware but that's it. IIRC the only special
requirement for BNEP is that the MTU should be configured to 1691.
(this is easy to check with hcidump)
