But under Linux it is not needed I presume......

NO.

Linrad uses waveInOpen with a WAVEFORMATEX or WAVE_FORMAT_EXTENSIBLE
format. New in Linrad-02.40. Before it was only WAVE_FORMAT_WAVEFORMATEX
but that does not work under Vista I have been told. Now Linrad
switches to WAVEFORMATEX if WAVEFORMATEX fails but when it happens,
24 bit does not work and one has to open two devices with two channels
in each one to get a four channel configuration.

I do not know much about Windows, but it does not seem reasonable 
to me.

What I would try is to find a computer on which neither EMU1212 nor
Patchmix has been installed. I would put the EMU1212 into that
computer and try to use the "Install new hardware" of Windows.
It should find the EMU1212 and then it would ask where to look for the
drive routines. They should be located somewhere on the CD that
belongs to the 1212. I find it difficult to believe that that
procedure would fail. If it works, Linrad should find the driver
and there should be no timing error.

OK. And how can you know that the de-install really is complete?
Make a simple test on an innocent machine first.....
