So, you're saying that either card reports as firmware version 6.04 on
one host, but as version 6.08 on another?

That's extremely bizarre.

Yes - by "must set ESSID", the message means that the firmware can't
cope with ESSID "any" in (IBSS) ad-hoc mode.  However it's not clear
that IBSS ad-hoc mode is really supported by this card - it should be
supported by firmware versions 6.06 and later, but it looks like the
firmware version might be misreported (I've never heard of version
6.08 vefore).
